In a large mixing bowl, combine ground turkey, finely chopped onion, minced garlic, chopped parsley, Worcestershire sauce, Dijon mustard, salt, black pepper, and optional smoked paprika. Gently mix the ingredients with your hands until just combined, being careful not to overmix.

Divide the mixture into four equal portions and shape them into patties about 1 inch thick, making a slight indentation in the center of each patty.

Preheat your grill to medium-high heat, or preheat a skillet over medium heat. If using a skillet, add a tablespoon of oil to prevent sticking.

Carefully place the patties on the hot grill or skillet, cooking them for 5-7 minutes on each side until golden-brown and the internal temperature reaches 165°F (74°C).

If you’re adding cheese, place a slice on each patty during the last minute of cooking and cover to help it melt.

Lightly toast your burger buns cut-side down on the grill or in a separate skillet for 1-2 minutes until golden brown.

To assemble each burger, place a patty on the bottom half of the toasted bun, layer with lettuce, sliced tomatoes, and your favorite condiments, then top with the other half of the bun.
