01 - Combine cranberries, orange juice, sugar, orange zest, and pinch of salt in small saucepan. Simmer over medium heat, stirring occasionally, for 10 minutes until cranberries burst and sauce thickens. Remove from heat and cool completely.
02 - Combine ground turkey, onion, garlic, egg, breadcrumbs, Dijon mustard, parsley, salt, and pepper in large bowl. Mix gently until just combined, being careful not to overwork the meat.
03 - Divide turkey mixture into 4 equal portions. Form each portion into uniform burger patties, pressing gently to create slight indentation in center to prevent puffing during cooking.
04 - Heat olive oil in large skillet over medium heat. Place patties in pan and cook for 5-6 minutes per side until golden brown and cooked through, reaching internal temperature of 165°F.
05 - Lightly toast burger buns in skillet or under broiler for 1-2 minutes until golden and crispy.
06 - Place lettuce on bottom bun, add cooked turkey patty, spoon cranberry sauce over top, and layer with red onion slices and tomato. Cover with top bun and serve immediately.
