It is a popular casserole from my childhood that usually uses the canned cream soup and the cheese tortilla chips loaded with carbs. I have successfully re-created this casserole into a keto, low carb, gluten free version that will top any old retro casserole made with canned soup!

I paired mine with some salad greens and the usual taco toppings like salsa, sour cream and black olives!

I mixed my chip selection up and used half taco flavor and half cheese flavor. Get a box from my link at the bottom of the recipe. It is more cost effective this way versus picking up in the store!
