Grilled Tuna Sandwich with Lemon-Chili Mayo

Grilled Tuna Sandwich with Lemon-Chili Mayo

Sturdy “country-style” bread works best for this healthy tuna sandwich recipe with watercress and chili-mayo. Eat the tuna sandwich warm, straight off the grill, or wrap it up and pack it in a cooler for a picnic dinner. Serve with grilled bell peppers drizzled with extra-virgin olive oil and vinegar and a glass of Sauvignon Blanc.

  1. 8 slices whole-wheat or sourdough bread
  2. 3 tablespoons canola oil
  3. 2 8-ounce tuna fillets, about 1 inch thick
  4. 1/2 teaspoon plus 1 tablespoon chili powder, divided
  5. 1/4 teaspoon salt
  6. 1/2 cup low-fat mayonnaise
  7. 1 teaspoon freshly grated lemon zest
  8. 1 tablespoon lemon juice
  9. 3 cups watercress or baby arugula, tough stems removed


  1. Preheat grill to medium-high.
  2. Lightly brush bread slices with oil. Brush tuna with the remaining oil and sprinkle with 1/2 teaspoon chili powder and salt.
  3. Grill the tuna, turning once, until cooked through, 4 to 6 minutes per side. Transfer to a clean cutting board. Grill the bread, turning once, until beginning to brown, about 1 minute per side.
  4. Combine mayonnaise, lemon zest, lemon juice and the remaining 1 tablespoon chili powder in a small bowl. Thinly slice the tuna with the grain.
  5. To assemble the sandwiches, spread about 2 tablespoons of the lemon-chili mayonnaise over 4 slices of bread. Top with about 3/4 cup watercress (or arugula), the tuna and the remaining slices of bread.
