Grilled Balsamic Portobello Mushroom Burger

This classic grilled portobello balsamic portobello mushroom burger packs a flavor punch from an overnight marinade! Pop on the grill for a summer vegetarian main. 

Happy July Fourth! We celebrated the holiday a day early on Saturday, so today we're spending the day working out in the backyard, which we're finally landscaping after living in our house the past five years. But if you've still got some celebrating in you, it's not too late to run by the store, grab a few portobello mushroom caps and get them marinating for a flavor packed vegetarian meal!
