I have a lovely tasting mushroom recipe but I will have to give you 2 recipes.
1st recipe doesnt use the barbeque but is needed for the second recipe.
get a saucer and put 2 table spoons of olive oil in it. Next crush a garlic clove and add to the olive oil. finally add about 10 olives and mix this around and serve as a Hors d'ouvre.
2nd recipe. when all of the olives have been eaten. Peel your mushrooms and put a melting cheese in side the mushroom cup. dip the bottom of the mushroom in the remaining olive oil and garlic mixture and pour a spot inside onto the cheese then place onto a barbeque until the cheese is melted
