The tangy, citrus-flavored mayonnaise pairs perfectly with grilled tuna for a delicious weeknight dinner that's ready in just 10 minutes. To add a charred flavor to the onions, throw them onto the grill with the tuna. The best way to prepare the onions for the grill is to cut a thin slice off each side of the onion. Then set the onion flat on the cutting board and cut into thick slices. Remove the outer ring from each slice and drizzle with a little olive oil before grilling. You can also grill the rolls. Serve sandwiches with coleslaw or fresh fruit.
