You can also take some of the fat from the ham-- small amount 1 to 2 inch pieces-render it in a heavy skillet- place the pineapple in the hot skillet searing it intil it has color on both sides--remove from the skillet to warm serving dish- Now grill the ham till it has some color on both sides. I cut my ham slices about 3/4 of an inch thick. I prefer to use a regular bone in ham not the slices. Anne
