Start assembling in a buttered baking pan
. You can layer any way you'd like, just make sure there's always sauce touching the tortillas so they don't get dry, and tear the tortillas so they completely covering each layer. (See the pictures below.) Here's how I did the layers: Tortillas, sauce, meat, cream cheese, tortillas, sauce, beans, peppers, tortillas, sauce, rest of the meat, tortillas, sauce, cheese. Basically keep layering everything in whatever order, and as you get to the top, just use up whatever you have left. Remember to make two pans at once if you have enough, because it really is a great time-saver later!
