How long doe it take to toast a sandwich on a grill?

About 3-7 minutes, depending upon the level of heat. If your bread burns before your cheese melts, the heat's too high. I've been mulling this question over, and I think it's like Einstein's theory of relativity. Einstein explained his theory this way: If you sit on a hot stove a minute, it seems like an hour. If you sit next to a pretty girl an hour, it seems like a minute. I think a grilled cheese sandwich takes a very short time if you want someone else to do it for you. It takes a long time if you're hungry and you have to do it yourself.
