Enchiladas, from the word "enchilar", meaning "to coat with chilli", are corn tortillas that have been ‘softened’ in hot oil then dipped in chilli sauce, filled, rolled and topped with more sauce and cheese before baking. The traditional enchilada sauce is made the same way as an Italian tomato pasta sauce is made, but spiced with cumin and a good shot of chilli. You can buy bottled enchilada sauce or deli-ready spicy Italian arrabiata sauce.
