Braised Vegetable Melange

Place the mushrooms in a small saucepan and cover with the stock and sherry. Bring to a simmer over medium-high heat and continue simmering until the mushrooms are soft, about 10 minutes. Remove from heat and let cool to room temperature.

Combine the carrots, onions, and tomatoes in a 13x9-inch baking dish. Add the mushrooms with liquid. Season with salt and pepper. (The vegetables may be prepared up until this point and then refrigerated overnight.)

The following day, bring the vegetables to room temperature. Preheat the oven to 325 degrees F. Cover the vegetables tightly with aluminum foil and bake 40 minutes. Uncover the vegetables and add the snow peas and frozen peas. Continue baking until vegetables are tender, about 20 minutes. Sprinkle the vegetables with parsley, if desired, and serve hot.
