Stir in the brown sugar and cook until the brown sugar is dissolved and the mixture is well blended. Arrange the pineapple slices in the bottom of a 9" round or square cake pan. Place marachino cherries in the centers of pineapple slices & in the spaces between the slices. Pour the brown sugar/margerine mixture in the cake pan, over the pineapple and cherries. Set aside.
