Grilled Tuna Sandwiches with Onions, Bell Peppers, and Chile-Cilantro Mayonnaise

Yield 4 servings (serving size: 1 sandwich)
The tangy citrus quality of the mayonnaise pairs well with the grilled tuna--a favorite of Marianne Legato. When the weather is nice, prepare this on the grill. Red bell peppers are a good source of antioxidant beta-carotene, and the amount of bell peppers in just one sandwich delivers almost a whole day's requirement for vitamin C.


  • 2 tablespoons chopped fresh cilantro
  • 6 tablespoons low-fat mayonnaise
  • 1 teaspoon ground ancho chile pepper
  • 1 teaspoon grated lime rind
  • 1 teaspoon fresh lime juice
  • 1/4 teaspoon ground chipotle chile pepper
  • 5 teaspoons olive oil, divided
  • 4 (1/4-inch-thick) slices Oso Sweet or other sweet onion
  • 1 red bell pepper, seeded and quartered
  • 1/2 teaspoon salt, divided
  • 4 (5-ounce) tuna steaks (about 3/4 inch thick)
  • 1/4 teaspoon ground cumin
  • 1/4 teaspoon freshly ground black pepper
  • 4 (2-ounce) sandwich buns
  • 4 red leaf lettuce leaves
