Make the Big Mac Sauce:

Mix Sauce Ingredients: In a small bowl, combine all the sauce ingredients: mayonnaise, pickle relish, ketchup, mustard, sugar, vinegar, paprika, onion powder, garlic powder, and white pepper. Stir until well mixed. Adjust the taste as necessary. Set aside.

Prepare the Tacos:

Prep Tortillas & Beef: Lay out the mini flour tortillas. Take the ground beef and season it with salt and pepper. Place about 1/4 cup of ground beef on each tortilla, spreading it out to cover the surface to the edges. You want the beef layer to be thin, mimicking the thin patties of a Big Mac.

Cook the Tacos:

Heat a Skillet: Place a skillet or griddle over medium-high heat. Lightly oil the surface.

Cook Beef Side Down: Place the tortillas beef side down on the skillet. Cook for 2-3 minutes until the beef gets a nice brown crust.

Add Cheese & Flip: Once the beef is cooked, flip the taco. Immediately place a slice of American cheese on the cooked beef side. Let it melt as the other side of the tortilla cooks to a golden brown, about 2-3 minutes.

Repeat: Continue with the remaining tacos.

Assemble the Big Mac Tacos:

Add Toppings: Open the tacos gently (they should be soft and pliable). Add shredded lettuce, diced white onion, and pickle chips on top of the melted cheese.

Drizzle with Big Mac Sauce: Spoon a generous amount of the Big Mac sauce over the toppings.

Serve: Serve the tacos immediately while warm and crispy.
