01 - Preheat oven to 425°F.
02 - Toss cut sweet potato fries with olive oil, sea salt, smoked paprika, and black pepper until evenly coated. Spread in a single layer on a baking sheet lined with parchment paper.
03 - Bake fries for 30 to 35 minutes, turning once halfway through, until golden and crisp at the edges.
04 - In a large bowl, combine ground turkey, finely chopped onion, minced garlic, chopped parsley, Dijon mustard, Worcestershire sauce, smoked paprika, salt, and black pepper. Mix gently until just combined.
05 - Shape the turkey mixture into four equal-sized patties.
06 - Heat olive oil in a large non-stick skillet over medium heat. Cook patties for 5 to 6 minutes per side until browned and fully cooked through (internal temperature 165°F). Optionally, add cheese slices to patties during the last minute of cooking.
07 - Lightly toast the whole wheat burger buns.
08 - Layer each bottom bun with a lettuce leaf, followed by a cooked turkey patty, tomato slices, red onion, pickles, and preferred sauces. Top with upper bun.
09 - Serve the assembled burgers immediately alongside the baked sweet potato fries.
