My husband described this as, "Birthday meal worthy," and since I cook for a living, he spends most of the year deciding on what, exactly, I'll be on the hook for during a celebratory meal. This Mongolian Beef has made the short list–he's in love with it. I have to agree, it's pretty fantastic. And since it only takes about 20 minutes, I hope it makes the final cut.
