Big bag of frozen stir fry vegies

Hi, I couldn't resist this at Costco today. I can make a simple stir fry, but wondering what works for others when using something like this. A good sauce recipe would be appreciated. Is there something else I can do besides stir fry? The contents are: brocolli, snap peas, baby corn, edamame, carrots, portabella mushrooms, water chestnuts, red and yellow bell peppers, shiitake mushrooms and green onions.
