You've definitely got my head turning on this one! Pineapple is such a great way to add that sweet and tangy note to a dish like this. This sauce sounds so yummy I would definitely do a few taste tests along the cooking process. ;) I am always a fan of bean sprouts, too. I have some broccoli sprouts for this week, but may have to do some mung beans again next week since yours look so crunchy, fresh and delish!
