In a large bowl, combine turkey with onion soup/dip mix. Mix thoroughly with your hands. (Don't be squeamish-it's the easiest way!) Evenly and firmly form the mixture into 5 patties.
Bring a grill pan sprayed with nonstick spray to medium-high heat. Place the burgers in the pan, working in batches as needed. Cover and cook until cooked through, about 6 minutes per side. Serve and enjoy!
