This tasty appetizer is quick to put together and since it has to be chilled, you get to make it ahead of time to take pressure off the rest of the dinner preparations.
Clean mushrooms and trim stems. Halve or quarter mushrooms if they are too large.
In a large skillet, over medium-high heat, sauté the garlic. Add vinegar and the next five ingredients, stir well. Add mushrooms. Cover, reduce heat and simmer 20 minutes or until mushrooms are tender. Stir occasionally.
Cool to room temperature. Place in airtight container and refrigerate for 8 hours or overnight.
Notes
For guests following a paleo diet, you may want to change the olive oil to a seed oil.
