Low-Carb Million Dollar Chicken Casserole - crustless chicken quiche that is great for lunch and dinner. Quiche is one of our favorite meals, and this is one of the best quiches that I've made. It took no time to whip together and tasted great. It is so light and fluffy and super cheesy! Chicken, mozzarella, eggs, cottage cheese, sour cream, cream cheese, garlic salt, onion powder, and pepper. Can make in advance & freeze for later.
