01 - In a small saucepan, combine cranberries, orange juice, sugar, orange zest, and salt. Simmer over medium heat, stirring occasionally, until cranberries burst and sauce thickens, about 8 to 10 minutes. Remove from heat and allow to cool.
02 - In a large mixing bowl, combine ground turkey, onion, garlic, parsley, Dijon mustard, Worcestershire sauce, salt, black pepper, and breadcrumbs. Mix gently until just combined. Shape into 4 equal patties.
03 - Heat olive oil in a large skillet over medium heat. Cook the turkey patties 5 to 6 minutes per side, until golden brown and internal temperature reaches 165°F.
04 - Optionally toast burger buns lightly.
05 - Place lettuce leaves on bottom half of buns, add cooked turkey patties, spoon cranberry sauce over patties, then top with sliced tomatoes and red onion. Cover with top bun halves.
06 - Serve immediately with extra cranberry sauce on the side if desired.
