Directions:

In a bowl, combine the flour, baking powder and salt. Add the milk, mayonnaise and egg; mix just until combined. Fold in the cheese and onions.

Spoon into a greased 9-inch round baking pan.

Bake at 425 degrees for 20-25 minutes or until a toothpick inserted near the center comes out clean. Cool for 5 minutes before removing from pan to a wire rack. Refrigerate any leftovers.
