Season the meat with salt and adobo.
Separate the meat into 4 oz balls.
Preheat the flattop grill or skillet. It needs to be hot and well oiled.
Use a piece of parchment paper and a burger smasher to push down on the 4oz patty until it is very thin and flat.
Place a tortilla wrap on top of the burger pressing into the meat and let it all cook through for a few minutes. The meat will brown.
Once the burger is browned and cooked almost all the way through, flip it (and the tortilla) over.
Remove the tortilla with the patty and place it on a flat surface. Add cheese, lettuce, burger sauce, and caramelized onions (optional) to the tortilla and wrap it up.
Place the wrap back on the grill or skillet and use the burger smasher to push the burger down and set the tortilla in place as it browns. After a minute or so, flip the wrap and repeat with the other side.
Cut the wrap in half, dip in more burger sauce and enjoy.
