1. In a skillet over medium-high heat, cook the beef, hot sauce, cayenne, and chili powder until the beef is browned.
2. Serve the beef, tortillas, tomato, lettuce, and salsa on separate plates, buffet-style. To make a burrito, place a couple of spoonfuls of ingredients in the center of a tortilla. Fold one edge up to make a bottom lip over the filling, then fold the sides in to overlap in the center, making a secure basket for the filling.
