Warm, creamy polenta pairs perfectly with an earthy blend of cremini and shiitake mushrooms. Alongside those mushrooms, shaved parmesan cheese adds a double dose of umami to this vegetarian main. Because the polenta is the base of the dish, look for a high-quality, stone-ground variety. That being said, grits will work just as welljust be sure to stir in butter and salt, just like you would with the polenta. When youre cooking the mushrooms, use the largest skillet you have, which will ensure that the veggies gets perfectly browned, and dont steam. Fresh baby greens, added just before serving, make for a beautiful presentation.
