1 can corned beef
1 c. grated cheese (American or cheddar)
2 hard boiled eggs
1 tbsp. minced onion
1 tbsp. chopped green pepper
2 tbsp. yellow mustard
1/2 tsp. salt
1/4 tsp. pepper
1 dozen hamburger buns

Preheat oven to 350 degrees. Crumble beef into large bowl. Then add other ingredients and mix. You can put mayonnaise or butter on the buns first or just spread the mixture evenly on the buns. Wrap in aluminum foil squares. Warm in oven 15 minutes. Can be frozen--takes 20 minutes when frozen. Or put in sandwich bags and warm in microwave.
