Bring a small pot of salted water to a boil and add mushrooms. Boil mushrooms for 3-5 minutes, or until tender. Drain the mushrooms.
Place mushrooms in a quart size mason jar, or other lidded container. Add remaining ingredients to the mushrooms, replace the lid and shake well to coat the mushrooms.
Refrigerate the mushrooms for several hours or overnight. Serve the marinated mushrooms at room temperature.
