Submarines

This is one I make if I have hot dogs, but no buns.  Don't leave out the mustard.  It really affects the taste.

Submarines
1 pkg. hot dogs
3 c. mashed potatoes
mustard
cheddar

Split the hot dogs from one end to the other without cutting all the way through, open them butterfly style.  Spread a little mustard down each one and top with a mound of mashed potatoes.  Top the potatoes with a slice of cheese.  Bake at 350 for about 20 min.  Just until potatoes are hot and cheese is melted.
