Appetizer rounds

1/3 cup mayonnaise
1/3 cup cheddar cheese, grated
1/3 cup mozzarella cheese, grated
3 green onions, sliced
2 cups biscuit baking mix
1/4 teaspoon garlic powder
1/2 cup boiling water

1. In a small bowl combine mayonnaise, grated cheddar cheese, grated mozzarella cheese, and sliced green onions; set aside.
2. Preheat the oven to 400 degrees. In a medium bowl mix together biscuit baking mix, garlic powder, and boiling water. Let stand until cool; turn onto a floured surface and shape into a ball. Roll out 1/8" thick and cut into 2" rounds with a floured cutter. Place 1" apart on ungreased baking sheets. Divide the topping over each round. Bake for 10 to 12 minutes, or until the topping is golden brown. Immediately remove from the baking sheet.
