01 - In a large bowl, gently combine ground turkey, onion, garlic, parsley, Worcestershire sauce, smoked paprika, salt, and black pepper without overmixing.
02 - Shape the mixture into 4 even patties, slightly larger than the buns to account for shrinkage during cooking.
03 - Preheat a grill or skillet over medium-high heat and lightly oil the surface.
04 - Cook patties for 5 to 6 minutes per side until golden brown and internal temperature reaches 165°F.
05 - Place a slice of cheddar cheese on each patty during the last minute of cooking and cover to melt.
06 - Toast the burger buns on the grill or in a toaster until lightly golden.
07 - Spread mayonnaise or burger sauce on the bottom bun, layer lettuce, turkey patty with melted cheese, tomato slices, red onion, and any additional sauces; top with the upper bun.
08 - Serve immediately with preferred side dishes.
