Turn your pan on medium heat.
Place your corn tortilla in the pan and heat them for 30-45 seconds on each side and set aside on a paper towel.
Crumble your chorizo spiced beef in the pan and start to brown it. When it's half way done throw in the onions, green pepper and jalapenos and saute until the meat is fully cooked.
Remove to a bowl.
Add your drained beans and canned tomatoes and mix well.
Pour 1/4 of your enchilada sauce into the bottom of the pan and swirl it around to coat it.
Place a layer of 3-4 tortillas on top (don't worry if there are some empty spaces it will be ok)
Sprinkle on 1/3 of your meat mixture and 1/2 cup of cheese
Repeat your layers of enchilada sauce, meat mixture and cheese 2 more times.
Place your pan in a 350 degree oven for about 20 minutes till the cheese is melted and it's heated through.
