Preheat your grill to medium-high heat.
In a large bowl, combine the ground turkey, red onion, green onions, red bell pepper, egg, olive oil, Worcestershire sauce, chili powder, paprika, coriander, and cumin.
Mix everything well until evenly combined.
Divide the mixture into six equal portions.
Shape each portion into a burger patty using your hands.
Place the patties on the preheated grill.
Cook for about 5-6 minutes on each side, or until the internal temperature reaches 165° F.
In a small bowl, mix the mayonnaise, chopped cilantro, and lime juice.
Spread this cilantro-lime mayonnaise on the burger buns.
Serve the cooked turkey patties on the buns with the mayonnaise.
