1 c. grated cheddar cheese
2 tbsp. mayonnaise
1/3-1/2 c. finely chopped black olives
2 tbsp. finely chopped onions
Party or cocktail rye bread

Mix cheese, olives, onions and mayonnaise, just enough mayo to get to spreading consistency. Spread on rye bread and broil or bake at 350 degrees until cheese melts.
