Serve this elegant mushroom caviar on toast points or thin baguette slices. For a gourmet twist, substitute verjuice for the lemon juice used to deglaze the pan. A sour condiment made from unripe grapes, verjuice is available in specialty stores.
1. Heat oil in large skillet over medium-high heat. Add onion, and sauté 5 to 7 minutes, or until softened. Stir in mushrooms, and cook 11 to 13 minutes, or until released liquid has cooked off.
2. Deglaze pan with lemon juice, cooking and stirring 1 minute, or until juice has evaporated. Add thyme and garlic, and cook 1 minute more. Stir in parsley just before serving. Serve warm or at room temperature.
