Heat a frying pan and melt the unsalted butter. While pan is heating re-heat ground beef mixture and set to the side. Heat flour tortillas and set to the side.
Cook each egg individually until over easy or medium.
Place flour tortilla on plate, add ground beef, place egg on top, and top with shredded lettuce, salsa, and crumbled cheese. Sprinkle hot sauce on top and black pepper on top of egg. Repeat until all tacos are made. Enjoy immediately.
