Carol, here's another variation. It's always a huge hit.

Hot Seafood Artichoke Dip

1 cup Parmesan cheese
1 cup mayonnaise
1 can artichoke hearts - chopped fairly fine
1 can small salad shrimp - drained
1 can crabmeat - drained
several shots of Tabasco sauce

Mix all ingredients together. Put into a microwave safe dish and heat. What hot, sprinkle with paprika or snipped chives for garnish. Serve with crackers.
