3 lbs. ground beef
1 tbsp. oregano
12 oz. sharp cheese, shredded
Salt and pepper to taste
1 lg. onion
1/2 c. catsup
2 tbsp. mustard
2 tbsp. Worcestershire sauce
Dash garlic salt, if desired
3/4 c. stuffed chopped olives

Brown meat and onions for about 20 minutes, add everything else except cheese. Mix together and remove from heat, then add cheese and mix again. Stuff buns, 18 to 24 depending on size of buns. Wrap each burger in foil and freeze at least 12 hours before using. When ready to use, place in 350 degree oven for 30 to 40 minutes. Remove from foil immediately when done or buns will sweat and toughen. (Be sure to freeze before using.)
