That sauce is in almost every grocery store...find it in the asian foods area.Since I couldn't find the sauce, I made a sauce very similar to this: http://www.food.com/recipe/the-best-sweet-and-sour-sauce-76003 and included pineapple, a green pepper and an onion. For flavor I added: garlic powder, mustard powder, sesame oil, ginger. With rice. It's good!
