You could try this with a standard grill, but they may not stay together. To cook on a standard grill, follow same directions only with a standard grill.
An excellent way to cook them on a grill is by planking. Just soak 2 untreated cedar, applewood, hickory, or mesquite planks in cold water for 1 hour. Air dry overnight, then place on the sides of one burner heated to medium low. Add 2 patties to each plank and insert a probe thermometer into one of them. Cover and cook until temperature is 140°F.
