Portobello Philly Cheese Steak Sandwich

Recipe courtesy EatingWell.com

  • 2 teaspoons extra-virgin olive oil
  • 1 medium onion, sliced
  • 4 large portobello mushrooms, stems and gills removed, sliced (Mom says you can add some thin sliced, cooked steak if you want)
  • 1 large red bell pepper, thinly sliced
  • 2 tablespoons minced fresh oregano or 2 teaspoons dried
  • 1/2 teaspoon freshly ground pepper
  • 1 tablespoon all-purpose flour
  • 1/4 cup vegetable broth or reduced-sodium chicken broth
  • 1 tablespoon reduced-sodium soy sauce
  • 3 ounces thinly sliced reduced-fat provolone cheese
  • 4 whole-wheat buns, split and toasted

Heat oil in a large nonstick skillet over medium-high heat. Add onion and cook, stirring often, until soft and beginning to brown, 2 to 3 minutes. Add mushrooms, bell pepper, oregano and pepper and cook, stirring often, until the vegetables are wilted and soft, about 7 minutes.

Reduce heat to low; sprinkle the vegetables with flour and stir to coat. Stir in broth and soy sauce; bring to a simmer. Remove from the heat, lay cheese slices on top of the vegetables, cover and let stand until melted, 1 to 2 minutes.

Divide the mixture into 4 portions with a spatula, leaving the melted cheese layer on top. Scoop a portion onto each toasted bun and serve immediately.
