4th of July Burgers with a Difference!

It's a hot 4th of July weekend here in Florida, so of course we wanted to be outside and grill. However, we're vegetarian, so ordinary burgers wouldn't do. The solution? Portobello mushrooms!

First, we marinated the mushroom caps in a mixture of olive oil, balsamic vinegar and herbs. Then, onto the grill. Once they were almost cooked, we added provolone cheese. Finally, we made our burgers with 3-grain bread, bean sprouts, lettuce and tomato. They tasted great, and are a wonderful alternative to meat!
