Prep Time20 minutes
Cook Time20 minutes
Total Time40 minutes
Servings: 2 servings

Ingredients

  • 2 medium Portobello mushrooms
  • 3 Tablespoons olive oil
  • 3 tablespoon balsamic vinegar
  • 1 tablespoon honey
  • 2 teaspoon minced garlic
  • Salt and pepper to taste
  • 1 cup cherry tomatoes or grape tomatoes
  • 2 slices Provolone cheese optional
  • 2 hamburger buns toasted (toasting is optional)
  • Optional garnish lettuce, onions etc.

Instructions

  • Preheat oven to 400F. Line a baking sheet with foil and set aside.
  • Clean mushrooms and remove stems and gills.
  • In a small bowl combine olive oil, balsamic vinegar, honey , garlic and salt and pepper. Pour the balsamic mixture into a zip-lock bag with mushrooms. Shake gently to coat the mushroom. Let marinate for at least 15 min. (as an alternative you can use a bowl or rimmed dish and spoon marinade over mushrooms) .
  • Cut tomatoes in half and place in a pyrex or other oven safe dish. Salt and pepper to taste. Set aside.
  • When mushrooms have finished marinating, remove from zip-lock (reserving marinade) and place open side up on foil lined baking sheet. Pour remaining marinade over dish of tomatoes.
  • Bake both for 20 min. (turning mushrooms over after 10 min.) until mushrooms are fully cooked and tomatoes are slightly browned . ( Broil for the last couple of minutes if you like your tomatoes more charred).
  • Cut buns in half, place bottom layer on a plate. Assemble burgers by layering on the bun, one Portobello mushroom, a slice of provolone cheese (if using) and top with half of the caramelized tomatoes and top half of bun. Add any garnish you like (lettuce, onions etc.)
