Heat a skillet over medium high heat.

Add the ground beef to a mixing bowl with the garlic powder and salt and pepper to taste. Knead to combine.

Separate the mixture into 8 evenly sized balls.

Press one ball of the meat mixture onto the front of a tortilla until it covers the whole surface.

Repeat step 4 with the remaining meat and tortillas.

Place the tortillas meat side down into the heated skillet. Cook for 3-4 minutes, smashing the tortillas flat with a spatula to flatten the burger.

Flip the burgers over, cover with a piece of American cheese, and cook for another 2- 3 minutes to crisp up the tortilla and melt the cheese.

Stir together the sauce ingredients in a bowl until well combined.

Spread some of the sauce mixture over each smash burger.

Top each burger with shredded lettuce and two pickle slices each.
