Portobello Mushroom Burgers [Vegan]

May is National Hamburger Month, but here at One Green Planet, I know we prefer veggie burgers. These portobello burgers are so filling and they are exceptionally tasty. Your omnivore friends will like them as much as your vegan friends do! Celebrate Memorial Day with a vegan BBQ and be sure to grill up these portobellos. Let your guests top them with their favorite burger toppings. Some of my favorites include avocado, onions, tomato, roasted red peppers, a grainy mustard, and vegenaise. You don't want to miss out on these!

Portobello Burgers are at the top of our Favorite Sandwich list. I just found some superdelicious flavored vinegars that would be cool to try with this...cherry vinegar and curry mango vinegar and some fabulous wine vinegars. Thanks for the recipe!
