Prepare the charcoal grill with a hot and medium side, then pre-heat the skillet.
Add the corn to the grill. Place the butter to melt in the skillet.
Add the green beans to the skillet. Salt and pepper the steak, then start cooking it.
Turn the steak when brown on one side. Turn the corn making sure it is cooking evenly. Move the beans to one side then add the scallops.
As items finish cooking move to the cool side of the grill. The trick is to get the meat cooked to your preferred doneness at the same time the scallops are ready. Be careful as scallops are easy to overcook.
