Potato Pie

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Preheat the oven to 350°F (175°C).
Line a baking dish with a layer of mashed potatoes.
Add slices of cold meats on top.
Sprinkle with butter, catsup, pepper, and salt.
Add another layer of mashed potatoes.
Repeat the layers until all ingredients are used.
Finish with a final layer of mashed potatoes on top.
Bake until warmed through.
