First - brown and drain the ground beef. Return it to the pan, and continue to fry on medium heat with 1 bell pepper, chopped fine, and 1 bunch of green onions, sliced (just the green part). Once the bell pepper is tender, add the pimientos and tomatos to sort of bind it up. Continue to cook untill most of the liquid is gone, then spread meat mixture in a 9x13 casserole. Second - layer the rest of the ingredients, in order. How freaking easy is that? Serve this with something you can dip into it, or if you are taking it to a potluck, you can just stick a spoon in it.
