In less than 20 minutes, you can have a hearty side dish or vegetarian meal. Tomato, basil and mozzarella taste fantastic on top of smoky, grilled portobello mushrooms. Enhance the flavor of the mushrooms with a drizzle of high-quality balsamic vinegar. To prepare the mushrooms, first rub off any dirt. Then, slice off the stems and remove the gills using a small spoon. Serve on light hamburger buns or whole wheat rolls for upscale portobello pizza burgers.


Portabella mushrooms

4 item(s), stems removed, wiped clean

Olive oil cooking spray

1 spray(s)

Shredded part skim mozzarella cheese

½ cup(s)

Garlic powder

¼ tsp

Dried oregano

1 tsp

Plum tomato

2 medium, sliced into 1/4-inch-thick slices


8 leaf/leaves, fresh (for garnish)


  1. Heat a grill or grill pan to medium-high heat.
  2. Coat mushrooms with cooking spray; place on grill, stem-side down, and cook, covered, 4 minutes. Uncover and using tongs, flip mushrooms; cook for 4 minutes more.
  3. Meanwhile, in a small bowl, combine cheese, garlic powder and oregano.
  4. After mushrooms have cooked for 8 minutes, remove them to a tray and reduce grill heat to medium-low. Fill each mushroom cap with about 2 tablespoons of seasoned cheese. Place mushrooms back on grill and cook, covered, until cheese melts, about 2 minutes.
  5. Remove mushrooms to a serving plate and top with tomato and basil. Yields 1 mushroom per serving.
