This is so good, and so easy to make it's ridiculous.
You'll need to cook 1 lb ground beef (or turkey) and cook 1/2 box of macaroni noodles.
Drain and season the meat with taco (or chili) seasoning, then layer macaroni, beans, tomatoes, onions, peppers, lettuce, meat and cheese in a 9x13 dish. Bake on 400 for about 10-15 minutes (just to melt the cheese). Serve with tortilla chips, and enjoy!
