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

There's a lot to love about these sandwiches: the onion and pepper grilled to caramelized perfection, the melt-in-your-mouth medium-rare tuna steaks, the spicy-tangy-creamy mayonnaise, and even the crunchy lettuce leaf on each bun. This dish is a great source of omega-3s and other healthy fats, but it has less than two grams of saturated fat per serving.
