In a bowl, combine flour, sugar, chocolate chips, walnuts, baking soda and salt. In another bowl, combine bananas and mayonnaise. Stir into the dry ingredients just until moistened.

Fill greased or paper-lined muffin cups three-fourths full. Bake at 375° for 20-25 minutes or until muffins test done. Press a cherry half, cut side down, into the top of each muffin. Cool for 5 minutes before removing from pan to a wire rack.

Yield: 1 dozen.
