Equipment

  • 32 oz wide-mouth mason jar
  • Plastic mason jar lid

Ingredients
 

  • 2-3 tbsp salad dressing
  • 1/2 cup sturdy vegetables carrots, chickpeas, or broccoli
  • 1/2 cup protein grilled chicken, salmon, or tofu
  • 2 tbsp cheese feta, cheddar, or parmesan
  • 1/4 cup cooked grains fully cooled quinoa, farro, or rice
  • 2 tbsp extras nuts or seeds
  • 1 1/2 cups leafy greens kale, spinach, or hydroponic lettuce

Instructions
 

Build the flavor base

  • Pour your favorite salad dressing directly into the bottom of a clean 32-oz wide-mouth mason jar, ensuring the liquid stays at the base.

Layer the sturdy middle

  • Add the sturdy vegetables like carrots or chickpeas first. These act as a physical moisture barrier to protect the other ingredients from the dressing.
  • Spoon in your chosen protein followed by the cheese. This keeps the savory elements in the center of the jar.

The grain barrier and the greens cap

  • Toss your fully cooled cooked grains with a small amount of oil and citrus zest, then add them to the jar to create a fragrant seal.
  • Scatter your extras on top of the grains, then pack the leafy greens tightly into the remaining space, pressing down gently to remove air pockets.

Seal and chill

  • Close the jar tightly with a lid and refrigerate immediately. Store upright until you are ready to serve.

Notes

Storage Tip: Always store your mason jar salads upright. If the jar is tipped over, the dressing can seep into the leafy greens and cause them to wilt prematurely.
Pro Tip: Use plastic lids instead of metal ones for long-term meal prep. The vinegar in most dressings can cause metal lids to rust over time.
Serving Tip: For the best texture, empty the jar into a large bowl and toss well. This ensures the dressing from the bottom is evenly distributed across all layers.
Preparation Tip: Ensure all cooked grains and proteins are completely cold before assembly. Any residual heat will create steam, which is the enemy of crisp greens.
