Directions

1. In a small bowl, combine all the burger sauce ingredients. Cover and refrigerate until ready to use.
2. In a separate bowl, season the beef with salt and pepper. Divide into 6 equal portions.
3. Top each tortilla with a portion of beef. Use a fork to flatten the beef into an even layer, leaving a ¼-inch border around the edges.
4. In a large skillet, heat 2 tablespoons of oil over medium-high heat. Once just below the smoking point, place 2 tacos beef-side down in the skillet. Press down firmly with a spatula or burger press.
5. Cook for 2 to 3 minutes, until the beef is browned and cooked through. Flip the tacos and top each with a slice of cheese.
6. Transfer cooked tacos to a baking sheet and repeat with the remaining tortillas.
7. Top each taco burger with sauce, pickles, lettuce, onion, and sesame seeds. Serve immediately.
