Nice tasty topping for our burgers, I used fried garlic from the Oriental store and just made half a recipe for the two of us; just one huge portabello. Also used aged cheddar slices; the touch of red wine was a nice touch, it added a lot of taste. We will probably use this recipe again, thanks for sharing.
