01 - In a large bowl, gently mix ground turkey, onion, garlic, parsley, Worcestershire sauce, Dijon mustard, smoked paprika, salt, and pepper without overworking the mixture.
02 - Divide the mixture into 4 equal portions and shape each into a patty slightly larger than the buns, as they will shrink when cooked.
03 - Preheat olive oil in a large skillet or grill pan over medium heat.
04 - Cook patties for 5 to 6 minutes on each side until well browned and fully cooked, with an internal temperature of 165°F.
05 - Place a slice of cheese onto each patty during the last minute of cooking, cover the pan, and allow the cheese to melt.
06 - Toast hamburger buns if desired.
07 - Spread sauces on buns, layer with lettuce, the turkey patty with melted cheese, tomato slices, red onion rings, and pickles. Top with the remaining bun halves.
08 - Serve immediately with preferred side dishes.
