Cook orzo according to package "al dente" directions. Rinse in a colander under cold water.
2 cups cooked orzo pasta
In a large bowl, combine orzo and pesto until well combined.
⅓ cup pesto
Stir in tomatoes, mozzarella, and basil.
1 cup cherry tomatoes, 6 oz fresh mozzarella, 1 tablespoon fresh basil
Use salad tongs to incorporate the fresh spinach and olive oil. Season with salt and pepper to taste.
2 cups fresh spinach, 1 tablespoon olive oil, salt and pepper
Notes
Season to taste and add additional olive oil or pesto if needed.
Storage: Make ahead or store leftovers in an airtight container in the refrigerator for up to 3 days. Spinach tends to wilt the longer it is stored, which is OK.
For a chopped salad texture, chop the spinach into smaller pieces before adding.
