Slow Cooker Porter Mongolian Beef

Winter was designed for breaking out the Crock Pot (or slow cooker, you know the brands). Slow cooked meats, especially when you start with a great cut like a flank steak, come out of the pot hours later so tender that a knife is not required. This take on Mongolian Beef uses a somewhat traditional sauce in the Crock Pot with a late addition of carrots for some sweetness. I served the beef over basmati rice. You can use any good porter, but we used the Black Butte Porter from Deschutes Brewing.
