Prepare a grill or a large skillet for cooking. It will need to be very hot.
In a medium bowl, combine the beef and seasoning (salt, pepper, garlic powder, Worcestershire sauce).
Prepare a large sheet pan with parchment paper, and lay down 6 tortillas (flat). TIP: You have to use flour tortillas. Corn does not work, as they don’t hold up.
Divide the meat mixture evenly onto each tortilla, smashing it down on the tortilla. Flatten the meat into a thin layer that covers the entire tortilla. TIP: We use a burger press but you can also use the bottom of a water glass or a spatula.
Sprinkle with the minced red onion, then using the press again, press the onions into the meat. You will have 6 tortillas with pressed beef (and onion) all the way to the edges.
Over high heat, lightly brush a skillet with oil/and or make sure the grill is smoking hot.
Place the tortillas beef side down, and using a spatula, continue to press and flatten the tortilla while it cooks for 2-3 minutes.
Next, flip the tortilla over and add a slice of the Sharp Cheddar Cheese to the hot meat.
Cover the pan with a lid, or cover the grill, until the cheese melts.
Remove and plate each Burger Taco, then add shredded Iceberg lettuce, chopped tomatoes, more red onion (optional), dill pickles, and burger sauce.
