This is a recipe from a community cookbook called "Sturbridge Kitchens" from Old Sturbridge Village in Ma. The ingredients are what I would consider, not very sophisticated but it is always HUGE hit at any get together. The only thing I have changed about it is, I use fresh mushrooms.
This is one of thoses simple recipes that just works just the way it is, and it freezes beautifully! YUM! —alflynn
Chopped White button mushrooms
Chopped pimento stuffed green olives
heaping 1/4 cup
Good quality mayonnaise (I use Hellmans)
Cocktail rye bread (freeze what you don't use)
Mix mushrooms with olives and enough mayonnaise to be fairly moist
Place a square of cheese to cover the cocktail bread and generously spread the mushroom mixture on the cheese
Toast under broiler until you see the cheese lightly brown and bubble on on the sides of the bread.
Keep a close watch on this as not to burn.
* this recipe doesn't have to be followed exactly as written. It's like telling someone how much mayo & celery to use in tuna salad...it just personal preference.
