You've got your meat - steak, chicken, pork, shrimp, fish, anything! - and usually with a few other toppings like sour cream, lettuce and tomato or something leafy if you want to pretend this is a healthy taco, maybe a sauce of some kind, usually spicyish. And cheese. Never forget the cheese. Then it's all wrapped up in a thin, bready wrap thing called a tortilla. Tacos! They're delicious, and they come in all kinds.
