01 - Set a large cast iron skillet or griddle over medium-high heat and allow it to preheat thoroughly.
02 - Divide ground beef into 8 equal portions, rolling each into a ball approximately 2 ounces in weight.
03 - Lay tortillas on a clean surface. Center one beef ball onto each tortilla and press firmly to flatten the beef, ensuring the meat covers most of the tortilla.
04 - Once skillet is hot, place the tortilla-beef assemblies meat-side down onto the surface. Firmly press with a wide flat spatula to achieve a thin layer. Season the beef side with kosher salt and black pepper.
05 - Allow beef to brown for 2 to 3 minutes or until deeply caramelized and edges become crisp. Flip to position the tortilla side against the skillet, top the beef with half a slice of cheddar, and cook an additional minute until cheese is melted and tortilla is golden.
06 - Transfer to a plate and repeat process with remaining patties and tortillas.
07 - Garnish each taco with shredded lettuce, sliced onion, tomato, pickles, and desired sauces such as burger sauce, ketchup, or mustard. Fold and serve promptly.
