01 - Preheat the oven to 425°F. Line a baking sheet with parchment paper. In a large bowl, toss the sweet potato fries with olive oil, smoked paprika, garlic powder, salt, and black pepper. Spread them evenly on the baking sheet.
02 - Bake for 25–30 minutes, turning halfway through, until fries are golden and crisp at the edges.
03 - In a large bowl, combine ground turkey, chopped onion, minced garlic, egg, breadcrumbs, Dijon mustard, parsley, Worcestershire sauce, salt, and black pepper. Mix gently until combined, avoiding overworking the mixture.
04 - Shape the mixture into four equal-sized patties.
05 - Heat olive oil in a large skillet or grill pan over medium heat. Cook patties for 5 to 6 minutes per side until browned and fully cooked (internal temperature 165°F).
06 - Lightly toast the whole wheat buns if desired.
07 - Place a lettuce leaf on each bottom bun. Top with a turkey patty, tomato slice, red onion, pickles if using, and your choice of sauce. Cover with the top bun.
08 - Serve immediately alongside the hot sweet potato fries.
