Linda's Enchiladas (Revised)
Add a chopped jalapeno with the onion and can of green chiles for some extra heat. You can cut up some green onion, black olives, or tomatoes to sprinkle over the top before or after baking depending on if you want them soft or not.
You can use either red or green enchilada sauce. I like the green flavor better; it gives a good Mexican flavor without being spicy.
If using corn tortillas, heat in oil just to soften before rolling. If you're using flour tortillas no need to heat in oil.
