Editor's Note: Grilled or roasted, portobello mushrooms are tasty no matter what! You can serve these roasted Portabello burgers as a part of a salad. This super easy recipe only needs five ingredients that you likely already have on hand. It will also be ready to eat within 30 minutes of roasting the mushrooms, making this recipe ideal for anyone who feels dinnertime can just be too hectic. The roasted mushroom caps can be stored and used at a later time, saving you even more time. If you're looking for a hearty vegetarian dish to serve at your next family get-together or Sunday barbecue, then this recipe is it!
My friend Susan Benett taught me how to cook a better portobello mushroom: remove the black insides. Without them, the mushroom stays drier (instead of waterlogged) and better able to hold ingredients. This burger is perfect for the mushroom lover who doesn't want all the carbohydrates found in bread. This calls for making an open-faced burger, but you can cook another four mushroom caps and place them on top, if desired.
