Prep the lettuce “buns.” Rinse and pat dry large lettuce leaves.
For extra structure, stack two leaves per wrap. Keep chilled so they stay crisp.
Mix the meat. In a bowl, combine ground meat with salt, pepper, paprika, minced onion and garlic (or powders), and a splash of Worcestershire. Add a beaten egg if using.
Mix gently—overmixing makes patties tough.
Form patties. Divide into equal portions (4 patties for 1 lb/450 g). Press with your thumb to create a small dimple in the center so they cook flat.
Heat your pan or grill. Warm a cast-iron skillet or grill over medium-high. Add a thin slick of oil to the pan (or oil the grates).
Cook the patties. Sear 3–4 minutes per side for beef (longer for turkey/chicken until fully cooked).
For cheeseburgers, add cheese in the last minute and cover to melt.
Rest briefly. Transfer patties to a plate and let rest 2–3 minutes. This keeps them juicy.
Make a quick sauce. Stir Greek yogurt with lemon juice, dill, pinch of salt, and a little mustard if you like. Or keep it classic with ketchup and mustard.
Assemble the wraps. Lay down two lettuce leaves.
Add sauce, patty, tomato, onion, pickles, and avocado if using. Top with another lettuce leaf or wrap tightly like a taco.
Serve immediately. Secure with a toothpick if needed. Add a side of crisp veggies or baked sweet potato wedges for a complete meal.
