2 cans (8 ounces each) crushed pineapple, well drained
Whipped topping, optional
In a blender, combine the milk, sugar, biscuit mix, butter, eggs, vanilla and, if desired, food coloring; cover and process until smooth. Sprinkle the pineapple into a greased deep-dish 9-in. pie plate. Pour batter over pineapple.
Bake at 350° for 40-45 minutes or until a knife inserted in the center comes out clean. Garnish with whipped topping if desired.
