Oh, yes. I have a sandwich grill. My "need to eat but what??" thing is to put cheese (whatever kind is already sliced, shredded, or otherwise in small pieces) between two slices of bread (or a split roll or whatever. If it isn't moldy, it's fine). Put it in the grill while I do something else, then pry the bread apart and squeeze in some relish.
It tastes different every time, but it's always tasty. :-)
Bread is cool. So versatile. I don't have a sandwich grill, just have to do the old-fashioned butter fry atop the stove. Still tastes great though.
The other day I had another thing I hadn't eaten in years: peanut butter, mayo, and sliced banana sandwiches. Yum!
Is your sandwich grill what I call a sandwich toaster? Mine only takes sliced bread though not a roll.
