Cut the polonies in half lengthwise. Score 3 or 4 deep lines across the polonies and decorate with pineapple pieces and cherries. Push two cloves into each onion half and add to the pan along with the bay leaves.
Mix the brown sugar mustard and pineapple juice to a think paste and pour over the decorated polonies.
Roast the “game on” in the oven for 40 minutes, basting frequently with the glaze and pan juices, until cooked through and golden-brown.
