My grandmother made hers like this:
1 pound lean ground meat
1 tsp. Horseradish
Salt & pepper
Garlic powder
Dash of Worcestershire sauce
Packet of Lipton onion soup
Evaporated milk. Mix it all up. And top it with either catsup or picante sauce. Bake at 350 for about 45 minutes.
For fun she buried a couple of hard boiled eggs in her loaf. Looked so pretty when it was sliced and it delighted my children.
