Ingredients

For Portobello Burgers

4 large (not baby) portobello mushrooms , stems removed and dirt rinsed away (see Notes)
4 tablespoons balsamic vinegar
1 1/2 teaspoons soy sauce
2 tablespoons olive oil
1/4 teaspoon ground thyme
1/4 teaspoon dried oregano
1/8 teaspoon black pepper
4 slices provolone or swiss cheese , optional
4 whole wheat hamburger buns or sandwich thins , optional
Grilled onion, fresh tomato, greens , optional
1 roasted bell pepper (see Instructions below)
1/4 cup homemade light pesto dressing (see Instructions below)
grilled sweet potato wedges (see Instructions below)

Instructions

Add portobello mushrooms to a resealable bag or shallow container. Top with vinegar, soy, oil and spices. Marinate in the refrigerator for 15-20 minutes, turning once to coat evenly.
Grill 3-5 minutes per side on indoor or outdoor grill, brushing with leftover marinade on each side as they cook (cooking time depends on how hot your grill gets).

To Serve

Top each burger with a slice of provolone cheese.
If desired, top with tomato and greens or grilled onion. To grill onion, slice in thick slices, brush with olive oil and throw directly on the grill 3-5 minutes per side.
Serve alongside a handful of my Grilled Sweet Potato Wedges.

To Finish

Finish each burger with 1 tablespoon of my Easy Pesto Dressing and 1/4 of a Homemade Roasted Red Pepper.

Notes

To clean portobello mushrooms, I like to use a wet towel to rinse away the dirt. Running or soaking in water can make a soggy mess.
