I still remember the first time I packed this Meal Prep Chicken and Spinach Salad with Strawberries for a week-long conference. It was one of those crazy-busy weeks where every minute between sessions was spent answering emails, and the hotel’s $18 wilted Caesar felt like culinary robbery. I tucked four mason-jar salads into my carry-on, convinced TSA would confiscate the balsamic. Not only did they sail through security, but colleagues kept eyeing my Technicolor lunch like it was edible confetti. By day three I was emailing the recipe to half the marketing team and fielding questions like “Do the berries get soggy?” (spoiler: they don’t if you layer smartly). Fast-forward two years and this vibrant, protein-packed salad is still my weekday workhorse—perfect for desk lunches, beach picnics, or those Tuesday nights when you want something fresh but refuse to turn on the stove. The sweet strawberries play off the savory grilled chicken, creamy goat cheese adds tang, and the poppy-seed vinaigrette ties everything together in a way that feels downright celebratory—no sad desk-lunch vibes allowed.

Ingredients You'll Need

Chicken: I reach for boneless skinless chicken breast because it grills in six minutes and shreds like a dream. Opt for organic if possible—better texture and zero rubbery after-bite. Thighs work too; just trim excess fat and add two minutes per side on the grill. Vegan friends swap in two cans of drained chickpeas tossed with smoked paprika.

Spinach: Grab the plastic tub marked “triple-washed” to save time. Look for bright green leaves without moisture pockets (slimy city). If you’re lucky enough to hit a farmers market, buy a generous bunch of young spinach; stems are tender and salad-ready.

Strawberries: Peak-season berries smell like, well, strawberries. Choose smaller, darker fruit—they’re denser and sweeter. Out of season, organic frozen berries (thaw and pat dry) rescue the dish without mush trauma.

Goat Cheese: Crumbled chèvre is convenient, but buying a 4-oz log and freezing for 15 minutes lets you crumble it exactly as coarse or fine as you like. Dairy-free? Sub ½ cup toasted pumpkin seeds for crunch and richness.

Almonds: Sliced, not chopped, cling to forkfuls better. Lightly toast in a dry skillet until fragrant; cool completely before adding to jars to prevent condensation.

Poppy-Seed Vinaigrette: Extra-virgin olive oil adds antioxidants while Dijon keeps emulsion silky. Avocado oil is a neutral swap if you prefer the spotlight on berries.

How to Make Meal Prep Chicken and Spinach Salad with Strawberries

Marinate the Chicken

Whisk 2 Tbsp balsamic vinegar, 1 Tbsp olive oil, 1 tsp honey, ½ tsp salt, ½ tsp pepper, and 1 clove grated garlic in a medium bowl. Add 1 lb chicken breast, coat well, cover, and refrigerate 30 minutes (up to 24 hours for deeper flavor). The honey encourages caramelization on the grill and balances tang from the vinaigrette.

Prep the Berries

Hull and quarter 2 cups strawberries. Toss with 1 tsp honey and juice of ½ lime; set aside 10 minutes. This quick maceration amplifies sweetness and forms a thin protective syrup that slows oxidation, keeping fruit bright for days.

Make the Poppy-Seed Vinaigrette

In a jam jar combine ⅓ cup extra-virgin olive oil, 2 Tbsp white balsamic, 1 tsp Dijon, 1 tsp poppy seeds, ½ tsp honey, ¼ tsp salt, and pinch of pepper. Shake vigorously 30 seconds until creamy and pale yellow. Taste and adjust sweetness; set aside for flavors to meld.

Grill the Chicken

Preheat grill (or grill pan) to medium-high, about 425 °F. Oil grates. Remove chicken from marinade, letting excess drip off. Grill 3–4 minutes per side with lid closed, until internal temp hits 160 °F. Transfer to plate, tent with foil, rest 5 minutes, then slice on the bias into strips. Resting allows juices to redistribute, ensuring moist bites even after refrigeration.

Toast the Almonds

Place ¼ cup sliced almonds in a dry skillet over medium heat. Stir constantly 2–3 minutes until golden and fragrant. Immediately transfer to a cold plate to stop cooking; cool completely.

Assemble the Jars

Use four 24-oz wide-mouth mason jars. Divide vinaigrette among bottoms. Layer in order: strawberries (drained), sliced chicken, goat cheese, toasted almonds, spinach, and finally a paper towel square on top before sealing. This sequence keeps greens from direct contact with moisture and preserves crispness.

Refrigerate & Serve

Chill upright up to 5 days. When ready to eat, unscrew lid, invert onto a large bowl, shake gently, remove jar, and enjoy. The dressing cascades through layers, coating every leaf without sogginess.

Expert Tips

Slice Evenly

Pound chicken to ¾-inch thickness before marinating; uniform thickness equals even grilling and no dry edges.

Jar Size Matters

Pints are tempting but too cramped; 24-oz jars allow shaking space for dressing distribution without bruising greens.

Paper Towel Trick

A folded paper towel on top absorbs condensation, giving you an extra two days of crisp lettuce.

Freeze Your Cheese

15 minutes in the freezer firms goat cheese so you can crumble pea-size pieces that won’t clump when jarred.

Overnight Marinade

If time allows, marinate chicken up to 24 hours; the acid tenderizes and infuses flavor that survives refrigeration.

Double the Dressing

Make a second batch of vinaigrette to keep in the fridge; it doubles as a marinade for shrimp or a dip for crusty bread.

Variations to Try

Spring Swap: Trade strawberries for blueberries and add ¼ cup fresh mint ribbons.
Keto Mode: Omit honey in both berries and dressing; replace almonds with macadamia nuts.
Mediterranean: Sub sun-dried tomatoes for berries, add olives, and swap goat cheese for feta.
Extra Crunch: Add ½ cup roasted chickpeas on top of almonds; they stay crisp for three days.
Vegan Power: Use crispy tofu strips dusted with smoked paprika and maple-Dijon vinaigrette.

Storage Tips

Assembled jars keep 5 days refrigerated at or below 38 °F. Store them toward the front of the middle shelf where temps are most stable. If you added avocado (not listed but a popular add-on), reduce storage to 3 days and press plastic wrap directly onto cut surfaces before jarring.

Dressing can be made up to 1 week ahead; shake before using. Cooked chicken stores 4 days on its own—great to double for quesadillas later. Freeze extra grilled chicken slices in a single layer on a parchment-lined sheet, then transfer to a zip bag; they’ll keep 3 months and thaw overnight in the fridge.

For desk lunches without a fridge, pack jars in an insulated lunch bag with a frozen gel pack; contents stay safely chilled for 4 hours. Never leave at room temp beyond 2 hours (1 hour if ambient temp exceeds 90 °F).

Frequently Asked Questions

Not if you keep it away from direct dressing contact. Layering spinach at the top and adding a paper towel prevents moisture buildup, so leaves stay perky the full five days.

Yes. Thaw completely, pat dry, and macerate as directed. They’ll be softer but flavor remains bright; ideal for off-season cravings.

Swap sliced almonds for roasted sunflower seeds or pepitas. Both add crunch and healthy fats without allergens.

Freeze the log 15 minutes, then crumble with your fingers while still firm. Dusting crumbles lightly in cornstarch also prevents moisture-induced clumps.

No. Mason jars are not microwave-safe due to metal lids and thermal shock. Transfer contents to a microwave-safe bowl if you prefer warm chicken; otherwise enjoy cold—flavors pop at room temp.

24-oz wide-mouth jars leave room for shaking and easy fork access. Pints work for side salads, but you’ll need to toss in a separate bowl.
