From the Wholefoods.com website: "Sweet and savory, this casserole is perfect for simple entertaining. Roasting the yams brings out their inherent sweetness, while the marinated tempeh imparts a savory note of tamari, mirin, garlic, and onion. Dressed up with a bit of ginger and cinnamon, this dish will be a holiday sensation." I really liked this, I used 3 grain tempeh instead of soy and I used about 4 yams instead of 2 and I baked it for close to an hour.
