Mushroom Polenta Canapés
Nutty Gruyère cheese complements earthy mushrooms. Prepare and chill the polenta up to two days in advance; broil close to serving. Make the mushroom mixture up to a day ahead. You can serve this as an appetizer with Spice-Rubbed Braised Beef, or as a simple side dish—just omit the mushrooms and cheese, cut polenta into 20 rectangles, and serve two per plate.
