Cannonballs (Hot Ham and Cheese Sandwiches)
A cannonball is ham and cheese sandwiched in dinner rolls buttered with a mustard-poppy seed compound. The buns get wrapped in foil and bake until they are little bombs of joy. The recipe makes plenty extra to store and make a quick from-the-freezer fix for another wintery night.
