A large (10") flour tortilla filled with any number of concoctions including beans, beef, pork-then sealed by tucking the ends under. They can be eaten like this or topped with salsa, lettuce, tomato, cheese, or guacamole. If fried, they are now called CHIMICHANGAS.
Skirt steak. Most associate 'fajita' with a taco or the strips of meat that go into the taco. Beef skirt steaks come from the outer covering of the breast near where the 'brisket" comes from. There are only 2 'skirts' per cow, and it wasn't that long ago that meat processing plants ground this up with the scraps as burger. It is a highly flavorful cut of meat as a result of the loose fat membrane that 'burns' off when cooked properly.
