Portobello caps make excellent mini casseroles. Here, they hold a tomato, cheese and olive stuffing that grills up to a smoky perfection. Serve them with whole-wheat couscous and a mixed green salad for an easy meal.

  • ⅔ cup chopped plum tomatoes
  • ½ cup shredded part-skim mozzarella cheese
  • ¼ cup chopped Kalamata olives
  • 1 teaspoon minced garlic
  • 2 teaspoons extra-virgin olive oil, divided

  • 4 portobello mushroom caps, 5 inches wide
  • 2 tablespoons lemon juice
  • 2 teaspoons reduced-sodium soy sauce

  • Ready In

  1. Combine tomatoes, cheese, olives, garlic, 1 teaspoon oil, rosemary and pepper in a small bowl.
  2. Preheat grill to medium.
  3. Discard mushroom stems. Remove brown gills from the undersides of the caps using a spoon; discard gills. Mix the remaining 1 teaspoon oil, lemon juice and soy sauce in a small bowl. Brush the mixture over both sides of the caps.
  4. Oil a grill rack (see Tip). Place the caps on the rack, stem sides down, cover and grill until soft, about 5 minutes per side. Remove from the grill and fill with the tomato mixture. Return to the grill, cover, and cook until the cheese is melted, about 3 minutes more.
  • Tip To oil a grill rack: Oil a folded paper towel, hold it with tongs and rub it over the rack. (Do not use cooking spray on a hot grill.
  • People with celiac disease or gluten-sensitivity should use soy sauces that are labeled "gluten-free," as soy sauce may contain wheat or other gluten-containing sweeteners and flavors.

Tip for buying the mushrooms: I got a sealed 2 pack at my store, and some of the 'shrooms were FLAT and others were a lovely cup shape. Next time I will buy singly so that I can choose only the cup-like ones. Additions: used a 4-cheese blend instead of mozz (asiago, provolone I think. . it's a Trader Joe's packet). I added about 2 tsp of capers, some chopped arugula) I also baked/broiled in the oven as other reviewers suggested.

So easy and good! I skipped the rosemary and baked them instead as it is winter and I didn't want to turn on the outdoor BBQ. I cooked them at 450 for 12 min with the soy sauce, lemon juice sauce, then added the other mixture and cooked for 10 more minutes. They were so delicious! I will absolutely make them again! Pros: The taste was fantastic and it was very easy

Great meal! I love this for a dinner meal! Quick and easy. I added more rosemary (about 1/2 tsp. dried rosemary). I made this using the broiler on low instead of the grill. I served it with couscous and a side salad as recommended. Delicious! Pros: Easy, healthy, quick

I went a step further and added spinach from one of your recipes. Filling and delicious. Food is never boring with your recipes.

This was excellent! Being vegan, I left the cheese off, but otherwise, it has great flavor! I ate one, and my husband ate the other three for lunch recently. This will definately be made again, and soon, esp with grilling season full on.

DELICIOUS!!! And quite filling -- easily a meal. As much as I love the smell of rosemary, I am not fond of the taste; so I substituted tarragon. Also added some cooked shrimp to the filling. Yummy!
