In a 9 x 13 baking dish, layer the ham slices overlapping in 2 rows. Top each slice of ham with a pineapple slice and a cherry in the middle of each pineapple ring. Cover with foil and bake for 15 minutes.
In a bowl, whisk together the brown sugar, apple juice and mustard. Uncover the ham and drizzle with the glaze. Continue to cook, glazing in 5-minute intervals, for an additional 20 to 25 minutes. Serves 9.
