This recipe was found in Robin Robertson's Vegan Planet. My hubby is a brewer, so I naturally gravitated toward this recipe. I think this recipe would be equally as good with sliced portabello mushrooms. It's all about the sauce, which is thick and delicious. The carmelized onions are what makes this so tasty, in my opinion. The note says to serve it over noodles and to wash it down with more of the beer that you use in the stew. I served it over mashed potatoes and a side of steamed broccoli and used (and drank) oatmeal stout. Yum.
