In a large bowl, combine all ingredients and mix thoroughly using your hands. Be careful not to over-knead the mixture as this can cause the burgers to be tough when cooked.
Form into patties about 3/4-inch thick. Prepare on a barbecue grill or skillet until the internal temperature reaches about 170°F.
Serve with traditional burger toppings, condiments, and your choice of rolls.
