• In a small mixing bowl, combine mayonnaise, relish, mustard, vinegar, paprika, onion powder, and garlic powder. Mix well until well combined and set aside.

The Burger Taco:

• In a medium bowl, add beef, salt, and pepper. Mix to combine. Divide beef into 8 equal portions and shape them into balls.
• Press each meatball down onto a tortilla, using your fingers to flatten it.
• To a large skillet (or a griddle), add a small amount of oil (about 1 teaspoon). Heat over medium-high heat.
• To the skillet, add the tortilla, meat side down. Use a spatula to press the beef down, making the patty larger and thinner, covering most of the tortilla.
• Cook the burger for about 1 ½ to 2 minutes until the beef begins to brown, pressing down to flatten further. Flip the tortilla and burger over. Sprinkle 1 tablespoon shredded mozzarella. Cover with a lid for another 1 ½ to 2 minutes, or until the burger is cooked to your desired level of doneness. Remove smash burger and set aside.
• Repeat cooking process for remaining smash burgers.
• Sprinkle smash burgers with lettuce, onions, and drizzle with prepared sauce. Add optional toppings as desired. Fold tortilla in half and serve.
