In a large bowl, combine ground turkey, breadcrumbs, Parmesan cheese, garlic, onion powder, salt, pepper, Worcestershire sauce, and parsley.
Mix until just combined, being careful not to overwork the meat.
Divide the mixture into 4 equal portions and shape them into patties.
Preheat a grill or skillet over medium heat.
Lightly oil the grill or skillet to prevent sticking.
Cook the turkey patties for about 5-7 minutes on each side, or until internal temperature reaches 165°F (74°C).
Toast the burger buns on the grill for a few minutes.
Assemble the burgers by placing the patty on the bun and adding desired toppings.
Serve immediately with your choice of sides.
Enjoy your delicious turkey burgers!
