    Instructions:

    :

    Prepare a grill with medium hot coals

    Clean mushrooms and remove stems and gills.

    Place mushrooms on a plate.

    In a small bowl, combine the oil, onion, garlic, pepper and vinegar. Pour mixture evenly over the mushroom caps and let stand for 1 hour.

    Lightly salt the inside of the mushroom.

    Stuff mushrooms with bread crumb mixture.

    Terri’s Tips:
    • Change the flavor of the mushrooms by changing the herbs;
    use rosemary or tarragon
    • Make homemade breadcrumbs from left over bread or buns
    • Add cooked, chopped bacon to the relish
    • Make appetizer size portions with smaller mushrooms
    • Don’t wash the mushrooms, they are like sponges and will
    soak up the water making them soggy and tasteless. Wipe them
    off with a damp paper towel
    • Salt the mushrooms prior to cooking, never add salt to the
    marinade. It will pull the moisture out of the mushroom
    ruining the texture.

    Cooking Wiser:

  • Substitute chicken broth for the butter in the stuffing
  • Use low fat cheese
