In food processor:

Grind 1 can Spam
Shred 1 lb. American cheese
Dice 2 hard boiled eggs

Put these ingredients in bowl and add:

1 (6 oz.) can tomato paste
2 tbsp. chopped onion (I use equivalent with dried, minced onion)
2 heaping tbsp. Miracle Whip

Mix all ingredients well. Mixture can be put on buns and wrapped in foil. Bake at 350 degrees for 15 minutes or it can be put on 1/2 of an open faced bun and broiled for 2 to 3 minutes.
