In a small bowl, whisk together olive oil, balsamic vinegar, honey, Dijon mustard, minced garlic, salt, and black pepper.

In each mason jar, start by adding 2 tablespoons of the dressing at the bottom.

Layer the salad ingredients starting with the heartier vegetables like cucumbers and carrots, followed by cherry tomatoes, mixed greens, and protein.

Top with feta cheese and walnuts.

Seal the mason jars tightly and store in the refrigerator for up to 5 days.
