My kids love Potato Dogs! They are quick and easy and a great way to use up leftover mashed potatoes. I sometimes will intentionally make extra mashed potatoes, just for these Potato Dogs.
2 cups mashed potatoes
1 cup cheese, shredded
Bring a pot of water to a boil and add hotdogs. Cook 5 minutes, or until heated through. Cut hotdogs lengthwise, cutting almost all the way through, but not quite. I cut mine until they would stay open, but were still attached at the bottom. Place hotdogs on a baking sheet. Spoon or pipe mashed potatoes onto the hotdogs (if they are leftover potatoes, heat them first), then sprinkle with cheese. Bake at 350 for 10 to 15 minutes until the cheese is melted.
