MASON JAR MEAL PREP: Delicious pesto and pasta with tomatoes and mozzarella.
Cook penne pasta and drain, reserving 1/4 cup of the water. You may cook the entire box and mix with the pesto recipe, however, you will only need a portion to serve two mason jars.
Prepare the pesto according to the recipe: Process in the food processor two cloves of garlic, 2 to 3 cups of fresh basil leaves and 1/4 cup of walnuts. With the blade running, pour in about 1/4 cup of olive oil. Add salt and pepper to taste and blend. Add about 1/2 cup of Parmesan cheese. Mix briefly. Blend in additional pasta water to desired consistency.
Spoon a generous layer of pesto on the bottom of a mason jar. Add a layer of halved cherry tomatoes, a layer of cubed mozzarella cheese, and some of the penne pasta. Shake right before eating.
Make as many jars as you like.
