I combined the olive oil , several cloves of minced fresh garlic, salt and pepper together and brushed it onto the portobellos. I guess the above mixture was a brush-on marinade. I put the portobellos aside while I prepared the other ingredients and then broiled the cap side first for about 2 minutes and the gill side, stacked with roasted red peppers, basil, cheese and tomato for about 5 minutes. I served these with the allrecipes.com Burger or Hot Dog Buns and these sandwiches came out great. - 09 Aug 2010 (Review from Allrecipes US | Canada)
Unbelieveable! Restaurant quality. I roasted a yellow pepper (only thing I had) and used one side of an everything bagel (again, only thing I had) and it was unbelieveable!! Didn't change anything else! Can't wait to make it again! - 20 Jul 2010 (Review from Allrecipes US | Canada)
Did some shopping yesterday and found some really nice portobello's and with nearly all other ingredients on hand, decided to give this recipe a try. I used thinly sliced red onion, a bit of garlic powder, forgot I was out of the fresh and tomatoes and basil out of my garden. The sandwiches were delicious and well seasoned. Very flavorful, easy, and a great substitute for a meatless meal. Adding this to our list of favorites. Thank you for sharing! - 11 Jul 2010 (Review from Allrecipes US | Canada)
