2 c. sharp cheese, grated
1 small can sliced black olives
2 tbsp. chopped onion
1 c. mayonnaise
Bacon, fried & crumbled

Mix all ingredients together, except bacon. Spread on party rye bread and sprinkle bacon on top. Bake at 300 degrees for 15 to 20 minutes. They may be prepared in advance. (Even better if frozen before baking.)
