Preheat the oven to 400. Spray an 8x8 baking dish with cooking spray.
Mix seasonings with cream cheese, sour cream, mayo, broth, and half the cheese.
Stir in the turkey and squash. Spread in the prepared casserole dish. Top with the remaining cheese.
Bake until hot, about 30 min.
Substitutions: You can swap the cheddar cheese for mozzarella or any other cheese that melts well. Cauliflower or broccoli work well in place of or in addition to the squash. Additions: Feel free to add in some crumbled bacon, cauliflower rice, other steamed veggies, etc. This base sauce is great to make up your own casserole combination.To Reheat: You can reheat the leftovers in the microwave for 1 - 2 minutes or until hot. Another option is to warm in the oven at 350 degrees for 10-15 minutes.
