01 - Preheat a large cast iron skillet or griddle over medium-high heat.
02 - Divide ground beef into 8 equal portions, forming each into a ball approximately 2 ounces in weight.
03 - Place a tortilla on your work surface. Center a beef ball on each tortilla, pressing to flatten so the beef covers most of the tortilla.
04 - Once the skillet is hot, position each tortilla with the beef facing down onto the skillet. Firmly press with a flat spatula to spread the beef into a thin layer. Immediately season with kosher salt and black pepper.
05 - Cook for 2 to 3 minutes until the beef develops deep browning and crispy edges. Flip the assembly so the tortilla contacts the skillet. Top the cooked beef side with a half-slice of cheddar cheese and cook for 1 minute to melt the cheese and lightly toast the tortilla.
06 - Remove each taco from the skillet and repeat the process with remaining patties.
07 - Top each taco with shredded lettuce, sliced red onion, tomato, pickles, and drizzle with burger sauce, ketchup, or mustard as preferred. Fold and serve immediately.
