A soft taco is a taco made with a warm, pliable tortilla rather than a fried, crisp shell. It's the everyday form of the taco in Mexico, corn or flour tortillas warmed on a comal or griddle and folded around a filling, as opposed to the hard-shell taco, which is largely an American invention.
Common fillings include seasoned ground beef or shredded chicken, pork carnitas, fish or shrimp, beans, and cheese, topped with lettuce, diced tomato, onion, cilantro, and salsa. Northern Mexican states favor flour tortillas, while central and southern Mexico favor corn.
Soft tacos are a staple of both everyday Mexican cooking and Tex-Mex menus, and are commonly served with rice, beans, or guacamole on the side.
