1 1/2 lbs. mushrooms, about 75 med.
4 oz. can shrimp
1 clove garlic, minced
1 golf ball size onion, minced
8 oz. cream cheese
1/4 c. mayonnaise
Salt and pepper

Cream all ingredients. Remove stems and stuff mushrooms. Can be prepared a day ahead. I chop the stems and put in the freezer for baked dishes.
