Grilled Portabella Burger

Ingredients:

4 portobello mushroom caps

2 tablespoons balsamic vinegar

1 tablespoon low sodium soy sauce

1tablespoon olive oil

1 tablespoon chopped rosemary

1-1/2 teaspoons steak seasoning like Montreal Steak 

    Grill Mates

4 thick slices red onion

4 ounces reduced-fat Swiss, sliced thin (Alpine lace)

4 thin slices tomato

1/2 avocado, sliced thin

Baby spinach

4 whole-wheat buns

Ingredients:

In a large bowl, whisk together vinegar, soy sauce, oil, rosemary, and Montreal steak seasoning. Place the mushroom caps in the bowl and toss with sauce, using a spoon to evenly coat. Let stand at room temperature for 20 to 30 minutes, turning a few times.

Heat the grill or indoor grill pan over medium heat. When hot, brush the grate with oil or lightly spray the grill pan. Place the mushrooms on the grill, reserving marinade for basting. 

Grill for 5 to 7 minutes on each side, or until tender, brushing with marinade frequently.

Top the mushrooms with cheese during the last minute of cooking. While the mushrooms cook, grill the onions about one minute on each side and grill the buns until toasted.

To finish, place the spinach and grilled Portobello mushrooms on the buns and top with the grilled onions, sliced tomato and avocado.
