These chubby sandwiches have shredded cheese on the outside, which melts into a crunchy sheath as they cook. We used a Wilton 4 1/2-in. cutter for the large sandwiches and a 3 3/4-in. cutter for the smaller ones (find both as part of a nested set on amazon.com). Make these festive Halloween sandwiches alongside a pot of tomato soup for an easy dinner if you're having guests over to trick-or-treat.
