In a large bowl, mix together ground turkey, bread crumbs, Parmesan cheese, egg, minced garlic, onion powder, salt, and black pepper until fully incorporated.

Shape the mixture into patties of desired size.

Preheat your grill or skillet over medium heat, making sure it is well-oiled to prevent sticking.

Cook the patties on the grill for approximately 6-7 minutes per side, or until the internal temperature reads 165°F (75°C).

Assemble your burgers on buns with lettuce, tomato, cheese, and any preferred condiments.
