In a large skillet, cook ground beef and onions until beef is thoroughly cooked and onions are translucent.
Add tomatoes, beans, enchilada sauce, and spices and heat through.
On each flour tortilla, spread on ⅙ of cream cheese and ⅙ of green chilies; fold the flour tortilla in half.
In a 9x13 baking dish, spread half of the meat mixture, then layer the folded tortillas over the meat mixture. Spread the remaining meat mixture over the tortillas. Bake, covered, for 20 minutes.
Uncover and sprinkle crumbled tortilla chips over top of meat, followed by the cheese. Bake for an additional 5-10 minutes or until cheese melts.
Notes
If you have cooked ground beef and onions in the freezer, use these and skip the first step. If your freezer stock is depleted, this would be a good time to restock.
