You know what I love? Recipes that are easy to make, are packed with veggies, make enough for leftovers, and can be cut into neat little squares. This Pesto Chicken Casserole checks ALLLL the boxes! I took a shortcut and used Trader Joe’s Vegan Kale Cashew Pesto in this recipe, but you could use homemade pesto or another brand (just make sure to check your labels if you’re sticking to Whole30!).
