This one is not a formal recipe. It's more of a guide. I've guesstimated amounts the amounts. Don't have beef -substitute with ground turkey or chicken or make it vegetarian (add small dices of squash, zucchini, mushrooms, or whatever else you have).
Chop the veggies. Saute the onion, jalapeno, and pepper until it begins to soften. Add the ground beef (or chicken or veggies) and spices to taste. Once the beef is browned saute the garlic. Add enough salsa to make a saucy mixture. Take off the heat.
Build your lasagna in layers. Use the tortillas for the noodle and layer the beans, meat mixture, and cheese.
Bake in a 350 degree oven for about 20 minutes or until hot and bubbly. Top servings with guacamole, sour cream, and extra salsa.
