While not as "hearty", a rice pilaf is beautiful. Long grain and wild rice, with almonds or pecans and pine nuts, chopped dried apricots, dried cranberries, and caramelized onions (chopped, not long stringy ones or they look like worms in the rice, just sayin'...). Season with a little maple syrup (yes, seriously!) lotsa sage, onion powder, black pepper. Deeee-lish and always finished at every holiday potluck, veggie or not.
I have even crumbled Field Roast Apple-Sage Sausage into bits, fried it a bit and added - and had omnis SWEAR it was "real" sausage.
