Take your ham and cheese sandwich to the next level by turning it into a slider. Fluffy potato dinner rolls are just the right size for a few bites. Heating these small sandwiches in the oven makes the rolls nice and crisp and the cheese melty and gooey. You can also make these sliders in a toaster oven if you have one. To make a whole bunch of sliders for a party, double or triple this recipe (to make 8 or 12 sliders) and heat them all on one rimmed baking sheet in the oven. Follow this recipe with your kids.
