A roasted red pepper sauce tops this hearty sandwich with a yummy crab filling. With almost no saturated fat, this is light because the mayonnaise has been replaced with non-fat plain yogurt, and it’s served on only half a bun! —Rosalind Pope, Greensboro, North Carolina


  • 1 large sweet red pepper
  • 1/2 cup fat-free plain yogurt
  • 1 teaspoon sherry or reduced-sodium chicken broth
  • 1 garlic clove, crushed
  • 1/2 teaspoon hot pepper sauce
  • 1/4 teaspoon salt
  • 1 small onion, finely chopped
  • 1 small sweet red pepper, finely chopped
  • 1 teaspoon canola oil
  • 1 large egg, lightly beaten
  • 3 tablespoons fat-free plain yogurt
  • 1/2 teaspoon Worcestershire sauce
  • 1 cup crushed saltines (about 30 crackers)
  • 1 tablespoon minced fresh parsley
  • 2 teaspoons Dijon mustard
  • 1/2 teaspoon seafood seasoning
  • 1/2 teaspoon paprika
  • Dash pepper
  • 1 can (6 ounces) lump crabmeat, drained
  • 4 large portobello mushrooms (4 to 4-1/2 inches), stems removed
  • 2 hamburger buns, split and toasted
  • 1 cup watercress


  1. Broil the large red pepper 4 in. from the heat until skin blisters, about 5 minutes. With tongs, rotate pepper a quarter turn. Broil and rotate until all sides are blistered and blackened. Immediately place pepper in a small bowl; cover and let stand for 15-20 minutes.
  2. Peel off and discard charred skin. Remove stems and seeds. Place in a food processor; add the yogurt, sherry, garlic, pepper sauce, and salt. Cover and process until blended. Set aside.
  3. For stuffing, in a small nonstick skillet, saute onion and the chopped red pepper in oil until tender. In a small bowl, combine the egg, yogurt, Worcestershire sauce, saltines, parsley, mustard and seasonings. Stir in onion mixture; fold in crab. Spoon filling into mushroom caps. Place in a 15x10x1-in. baking pan coated with cooking spray.
  4. Bake at 400° for 15-20 minutes or until stuffing is golden brown and mushrooms are tender. Serve on bun halves with watercress and reserved red pepper sauce.
