My family loves this. It is pretty healthy. I only use organic vegetables and meat. You may use Ground Beef if you choose. Any type of tomato paste will do. Use a small can. Any type of cheese will work. I use 1 cup of Sharp Cheddar cheese and 1 cup of Monterey Jack cheese. Use whatever you want. But Swiss is not recommended. I use stone ground tortilla chips from Trader Joe's. Tostito's works great too. I don't know how big the bag is in weight but just use the medium-ish sized bag. Since Zaar won't let me put that, I'm going to guess about 20 ounces. I use Tapatio brand for Hot Sauce. I hope you enjoy this recipe.
