I warmed it on the stovetop (not microwave) and found it lacking, but acceptable.

After adding:

• tamarind paste,
• onions,
• bell peppers,
• a thai hot pepper,

and then topping with:

• cilantro,
• fresh lime, and
• some chopped up roasted peanuts,

... the additions (standard ingredients) made it much better.

Still, it was missing the contrast of bean sprouts. It isn;t the same without them and if I'd had bean sprouts, I would have added, but at that point I might have opted to just make my own pad thai -- which would have tasted better for almost the same amount of cook/prep time.
