I adapted this off the drweil.com forums. While it looked a little like gray mush, it turned out to be filling and tasty.
2 quarts veggie stock
2 cups sliced mushrooms (I used portobello)
2 handfuls dried shiitake mushrooms, crumbled
3/4 cup barley
3/4 cup dry lentils
1 tsp. garlic powder
3 bay leaves
1 large pinch each dried basil & sage
nutritional yeast, salt and pepper to taste
Combine everything in a crockpot, cover, and cook either 4-6 hours on high or 10-12 hours on low. Remove bay leaves before serving.
