Preheat oven to 350°F. Combine olives, green onions, butter, mayonnaise, cheese and spices in a bowl and mix well. Slice bread in half lengthwise and place halves on a baking sheet. Spread olive mixture evenly over bread. Bake for 20-25 minutes or until cheese is melted and topping is golden brown. Remove from oven and cut into slices before serving.
