Peel 4 medium large potatoes and grate directly into 1 cup of milk in a well buttered 8 inch square baking pan.
Grate a small onion into the milk and add 3 Tbsp chopped green pepper, grated cheddar cheese, salt and pepper to taste. Beat 3 eggs well and combine. Dot with 2 tsp of butter.
Bake at 350 F for about 50 minutes to 1 hour or until the pudding is richly browned.
