Preheat grill to medium-high heat.
Using your hands, mix together ground turkey, pesto, cilantro, green onions and salt and pepper. Pat into 4 patties, making a little indentation in the center of each patty.
Place onto preheated grill and cook for about 5 minutes on each side, or until cooked through.
Place each patty on a bun and top with mozzarella, tomatoes and any other favorite toppings! Devour and enjoy!
