Biscuits are wonderful at any time of day, and for any occasion. In this recipe, we've turned them into convenient slider-sized sandwiches, perfect for feeding a crowd. The arugula and red pepper jelly dress the sandwiches up for a more sophisticated crowd; but the more traditional southern-style version with just ham is equally delicious, thanks to the double slather of melted butter that goes onto the biscuits before and after baking.
