Combine first 11 ingredients. Divide mixture into 6 equal portions, shaping each into a 1/2-inch-thick patty.
Place patties on a grill rack coated with cooking spray; grill 7 minutes on each side or until a thermometer registers 165Â°. Remove from grill; let stand 5 minutes.
The original recipe called for finely chopped peanuts and 1-1/2 tablespoons of brown sugar. The peanuts added a weird texture so next time try the peanut butter and use the reduced amount of brown sugar or less.
