Fresh produce hot off the grill makes an unbelievable sandwich. I use an indoor grill pan mainly because the onions can be hard to control on a grate-style grill (but you could poke a skewer through them to keep them from slipping through the grate). To make this off-season, you could mix some chopped sun-dried tomatoes (instead of fresh) into the goat cheese. For small children, this is surprisingly palatable and very healthy.
