In a large bowl combine the turkey, zucchini, breadcrumbs, pesto, granulated garlic, onion powder, salt and pepper. Use your hands to gently combine the mixture.

Divide the turkey mixture into fourths and form into evenly shaped patties. Preheat your grill or skillet to medium-high heat and oil the grates or skillet. Cook the burgers for about 5 minutes then flip over and cook another 5 minutes or until the internal temperature reaches 165° F. and the middle is no longer pink. During the last minute or two of cooking add the mozzarella slices. Let the burgers rest for 5 minutes.

Serve the burgers on toasted/grilled buns topped with mixed greens, a tomato slice and an extra drizzle of pesto.
