In a large bowl, combine all ingredients together and mix well.
Layer it in a 13x9 dish (smaller if you want it thicker, but it will take longer to bake, or bigger or more shallow dish to be crispier and it will take a little less time to bake)
Bake at 375 for 45 minutes, until the cheese, is all melted and bubbly and the inside center of the dish is thoroughly hot.
Notes
Add your favorite protein to make this into a main dish, 2 cups cooked shredded chicken, pork, beef, ham, or sausage are all good options.
