Marinated Mushrooms

1/2 cup red wine vinegar
2/3 cup extra virgin olive oil
1 teaspoon oregano
1 garlic clove (crushed)
1/2 teaspoon salt
1/2 teaspoon sugar
1/2 teaspoon pepper
1 lb mushroom
1 tablespoon lemon juice
pinch of red pepper flakes - optional

Mix everything and let sit overnight.
You may store in refrigerator, but let them warm to room temperature before eating so they don't congeal.
