.

Ingredients

 * 4 5-inch portobello mushrooms, about 1 lb., stemmed
 * 1 recipe Sesame Ginger Marinade
 * 4 whole-wheat buns or hard rolls, split and lightly toasted
 * 1 Tbs. balsamic vinegar
 * 3 Tbs. olive oil
 * 2 tsp. Dijon mustard
 * 1 small bunch arugula, stemmed, leaves torn in half (2 cups)
 * 8 oz. soft goat cheese

Directions
1. Hold a mushroom, cut side up, in your hand. Using small sharp knife, carefully scrape to remove most of dark brown “gills.” Repeat with remaining mushrooms.

2. Prepare marinade in large, shallow glass dish. Add mushrooms and turn to coat. Let mushrooms marinate at least 30 minutes or up to 4 hours.

3. In medium bowl, whisk together vinegar, oil and mustard to make dressing. Season with salt and pepper and set aside.

4. Prepare hot charcoal fire or preheat gas grill on high. Grill mushrooms, turning often, until tender and grill-marked, about 10 minutes. Lightly toast rolls, if desired.

5. To assemble sandwiches, spread goat cheese on both sides of rolls. Arrange mushrooms on bottom of each roll. Add arugula to dressing in bowl and toss well. Place arugula leaves on top of each mushroom, cover with bun tops and serve.
