If using charcoal, start BBQ grill 3 hours prior to dinner
time.
When grill has been heating for 30 minutes, scrub potatoes
and wrap in foil.
Place potatoes in center of grill over hottest part of
the coals. Close cover.
When potatoes have roasted for 45 minutes, flip and move
to the edges of grill. Turn so that the sides of the potatoes
that had faced outward, now face inward. Continue to cook
with cover in place.
One hour before dinner time, prepare ham and pineapple.
Tear off a large piece of aluminum foil and place on a
flat surface.
Cut ham into slices and place in the center of the aluminum
foil.
Cut onions and green pepper into slices and place on foil
with ham.
Cut pineapple into slices and place on top of vegetables.
Mix together pineapple juice, cornstarch, soy sauce, mustard
and red pepper flakes.
Turn up edges of foil and pour sauce over the top of the
ham. Fold foil tightly over contents and press edges together
to form a flat package.
Place foil package onto the center of the grill. Roll
potatoes once more to cook evenly. Cover and cook for about
40 minutes.
When vegetables are tender, serve ham and pineapple with
roasted potatoes.
