Kristin,
I am definitely a fan of corn tortillas. I have been thinking of trying to make enchiladas from scratch with homemade corn tortillas. The problem is that the homemade tortillas will be more difficult to roll since they are usually thicker. Making the sauce is not as difficult, but then, like spaghetti sauce these days, there are too many good options available from the store.
These are big and hearty enchiladas, unlike the thin flat variety you get at Mexican restaurants, even here in Southern California.
Dave,
I used sauce from a can. I had a large can of La Victoria Red, which is my favorite, and a small can of Old El Paso, because they did not have La Victoria in the small cans.
The Old El Paso was thinner and smelled different.
This is quick comfort food. Cook the meat and onions, assemble, and melt the cheese. I cooked that big pan last night. There is one serving left. I just finished eating mine for dinner after having them for breakfast. I don't even heat them up when eating left overs. They are like cold pizza.
