Meatless Mondays: Open Faced Grilled Portobello Sandwich

I love, love, love mushrooms. I used to only eat button mushrooms, but then I had my first taste of a portobello and fell in love. One day while watching Rachel Ray, I saw her make a sandwich with a large portobello cap as the meat and I was intrigued. Could you really make a sandwich with a mushroom cap? That was when I discovered Meatless Mondays in my home! Here is my recipe for an Open Faced Grilled Portobello Sandwich.
