Heat vegetable oil in wok over medium-high heat. Stir in marinated pork pieces, ginger, and chile paste. (Discard remaining marinade.) Mix in teriyaki sauce, and increase heat to high; cook, stirring constantly, until pork is white. Stir in peppers, and continue to stir fry until most of the liquid has evaporated. Top with toasted almond slivers and fresh mint.
