This is a variation of a recipe I remember making as a kid. We used the Betty Crocker recipe cards and I remember being very careful not to burn them under the broiler!
Hot Dog Cheesies
One of each item per person.
Bring the hot dogs to a boil in clean water, and then let simmer 6 - 8 minutes. Meanwhile, lay the bread slices on a cookie sheet. Spread or drizzle mustard down the middle lengthwise. When the hot dogs are fully boiled, remove to a plate with a paper towel to absorb excess water. Lay on the mustardy bread. Drizzle or spread melted butter down the sides of the bread alongside the hot dog, on either side. Place a slice of cheese over the top (if it is not processed cheese, it will topple like a see-saw - that is okay!).
