8 eggs, heated
1 teaspoon salt
1/2 teaspoon ground black pepper
3 (14 ounce) cans diced cooked potatoes
2 cups mozzarella cheese, shredded
1/4 cup shredded Cheddar cheese
Preheat oven to 350 degrees F (175 degrees C). Heat the roast in the oven for about 15 minutes, or until cooked through.
Meanwhile, bring a large saucepan of water to a boil. Add potatoes and cook until tender but firm, about 10 minutes. Transfer potatoes to a large (8 inch) glass serving dish, sprinkle with salt and pepper and bake until potato is tender and firm, about 15 minutes. Cool, slice and serve.
