01 - In a large bowl, combine ground turkey, chopped onion, minced garlic, parsley, Worcestershire sauce, Dijon mustard, smoked paprika, salt, and black pepper; mix gently until just combined to preserve moisture.
02 - Divide the mixture into four equal portions and shape each into patties approximately 3/4 inch thick.
03 - Heat olive oil in a large skillet over medium-high heat or preheat grill to medium-high.
04 - Cook patties for 5 to 6 minutes per side until golden brown and internal temperature reaches 165°F (74°C).
05 - During the last minute of cooking, place a slice of cheddar cheese on each patty and cover to melt.
06 - Lightly toast burger buns if desired for added texture.
07 - Layer lettuce on bottom bun halves, top with turkey patties and melted cheese, followed by tomato slices, red onion, and pickles; add preferred condiments and finish with top bun.
