Make the Big Mac sauce first by stirring all ingredients together in a bowl until combined. The original Big Mac sauce doesn't have ketchup but you can taste and add it in if you prefer. Set aside in the fridge.
1/3 cup mayonnaise, 2 tbsp sweet pickle relish, 2 tsp mustard, 1/2 tsp apple cider vinegar, 1/2 tsp onion powder, 1/2 tsp paprika, 1/2 tsp garlic powder, Optional: 1-2 tbsp ketchup
Have your shredded lettuce and pickle slices ready for serving. The tacos will cook fast and you want to add the toppings before the dish gets cold.
2 cups shredded iceberg lettuce, 16 slices dill pickles
Place tortillas down flat, then divide ground beef into 8 equal portions. Roll each portion into a ball and place at the center of the each tortilla.
8 small tortillas, 1 lb lean ground beef
Press the meat flat into a circle until it almost reaches the edge of the tortilla. Sprinkle the meat with salt and pepper.
Salt and pepper
Heat a large nonstick skillet over medium high heat and add a thin layer of oil. You can also grill these - heat the grill to medium high then grease the grates.
Avocado oil
Once the oil starts smoking, place the tortillas down meat side down. Fit as many in the pay you can without overlapping (you'll cook these in batches). Press down with a spatula and cook for 2 minutes until the meat gets golden brown.
Flip the tortillas, and add a slice of American cheese on top. Cover for 1-2 minutes until the cheese melts.
8 slices American cheese
Remove from the pan or grill, then repeat with the rest of the tortillas. You can keep the cooked ones in a 200 degree oven so they stay warm until ready to eat.
Top with pickles, shredded lettuce, and a drizzle of Big Mac sauce. Enjoy!
