Step 1

Prepare the sauce by combining all the ingredients in a small bowl.

Step 2

Divide the ground meat into 12 equal portions, approximately one small handful each, and shape them into balls.

Step 3

Take a small flour tortilla and place a ball of ground beef on top. Flatten the beef until it covers the edge of the tortilla in a thin layer. Sprinkle with a pinch of salt and pepper.

Step 4

Heat a pan over medium-high heat. Add 1/2 tsp of vegetable oil. Put the tortilla with the meat side down onto the pan. Use the back of a spatula or a burger press to press down, creating a smashed burger effect. Cook for 3-4 minutes until the ground beef is browned.

Step 5

Flip the taco over so that the tortilla side is down. Place a slice of cheese on top and allow it to melt for about a minute.

Step 6

Remove from heat. Add diced onion, shredded lettuce, pickles, and the Big Mac sauce as toppings. Enjoy the taco while it's still warm!
