Use 80/20 ground beef to form into balls and flatten them onto small flour tortillas.
Bring a cast iron skillet to 400F and place the meat side of the tortilla directly onto the skillet with no oil.
Smash it down for a few seconds, then let it cook until the burger is pretty much done.
Flip it to the tortilla side, top with a slice of American cheese.
Once the cheese is melted and the other side is crispy, remove and assemble with shredded lettuce, pickle slices, and the special sauce.
Make the special sauce by mixing together: 1 cup mayo, 3 tbsp ketchup, 1 tbsp dijon mustard, 2 tbsp diced onion, 1 tbsp relish, 1 tbsp white vinegar, 1 tbsp garlic powder, 1 tsp paprika, and 1 tsp each of salt and pepper.
