  • 4 large portabello mushrooms, stems removed
  • 1 medium red onion, cut into eight slices
  • 1/4 cup reduced-fat red wine vinaigrette
  • 4 small tomatoes, each cut into four slices
  • 8 fresh basil leaves
  • 1 cup crumbled goat cheese
  • 2 tablespoons minced fresh thyme
  • Salt and pepper to taste


  1. Place mushrooms, onion and vinaigrette in a large resealable plastic bag. Seal bag; toss well to coat. Refrigerate 30 minutes. Drain and reserve marinade.
  2. For grill, coat grill rack with cooking spray before starting the grill. Wrap marinated onion slices in heavy-duty foil and place on medium-hot grill. Place mushrooms, gill side down, on grate. Grill both for 5-7 minutes; turn. Grill 5-7 minutes longer or until juices accumulate in the mushroom caps. Remove onions and mushrooms from grill; drain and reserve any juices from onions and mushrooms.
  3. For microwave, place onion slices and mushrooms, gill side up, on a microwave-safe plate. Cover and microwave for 3 minutes. Let stand for 30 seconds. Drain and reserve any juices.
  4. To serve, place each mushroom cap, gill side up, on a serving plate. Layer each with tomato, onion slices and basil. Sprinkle each stack with cheese and thyme. Combine reserved vinaigrette and cooking juices; drizzle over each stack. Season with salt and pepper. Serve warm.
