the kind without the hollow puff and with a small hole pinched in the middle (to prevent excessive rising)? These are used for hefty sandwiches, mainly used for the famous hotdog or sausage sandwiches by the reknowned Jimmy Buff's (etal) of Newark, N. J. Usually about 7" - 8" diameter and ~1.5" thick. They are cut in half and opened in the middle to stuff the dogs, peppers, onions and sliced potatos in. Best hotdog or sausage 'wich I ever had!! Like to see some techniques used.
