Turn the mixture into a greased baking dish.
Bake
Brush the top with melted drippings.
Bake in a moderate oven at 350°F (175°C) for 25 minutes.

- Mashed potatoes
- Form the bulk of the loaf and hold the mixture together as it bakes.
- Canned tomatoes
- Add moisture and gentle acidity that keeps the loaf from drying out.
- Ground peanuts
- Add body and a rich, nutty flavour that gives the loaf substance.
- Minced onion
- Adds aromatic flavour that deepens the savoury taste of the loaf.
