The hubby was making grilled cheese one day for the kiddos and made this for himself. We're on a big swiss cheese kick so we also had these for dinner one night recently. They're very yummy!
Spread two pieces of bread with butter. Place one slice butter side down in hot skillet. Top with a few slices of turkey (or ham or roast beef, whatever your choice may be), and a slice or two of cheese (in this case, Swiss). Place other slice of bread on top. Flip and finish cooking other side.
I added a bit of mayo to the inside of mine, as well as a few slivers of onion. Then we dipped the sandwiches in honey mustard.
