Place the ribeye in a large resealable plastic bag. Add steak seasoning, soy sauce and oil. Marinate for at least one hour or up to four.
Preheat grill over high heat. Once the grill is very hot, place some onions on the grill. Move them around to prevent them from burning. Push the onions to the sides of the grill. Put a few dashes of Worcestershire sauce on the grill top and place a few slices of steak over top. Flip them once brown on one side. Note: the steak will cook very quickly.
