mexican cornbread casserole, not sure how authentically mexican this one is but imagine everything you put into a taco, now put all of that into a casserole dish, cover with cornbread dough and bake. Keeps ya full and warm for a long time.
tortilla soup comes to mind along with menudo (the soup not the band) but I've never been a real fan of either so I don't have any advice for recipes
One of my favorites is equal parts red rice and re-fried beans stirred together, add cheese and salsa to taste then use corn chips to scoop up the goodness. This is normally how I finish my meals at the local mexican restaurant; eat the enchiladas and tamales first then stir everything else together and devour using chips.
