Reinvent a traditional nicoise salad by tucking it into a sandwich. Here, we've piled tuna, eggs, olives, and onions between slices of crusty ciabatta.

Ingredients

½ white onion, thinly sliced
½ red onion, thinly sliced
¼ cup plus 4 teaspoons extra-virgin olive oil
2 tablespoons red wine vinegar
Coarse salt and freshly ground pepper
2 jars (7 ounces each) best-quality tuna packed in olive oil
1 tablespoon fresh lemon juice, plus lemon wedges, for serving
4 small ciabatta rolls, split horizontally
2 heads Bibb lettuce, leaves separated
½ cup nicoise olives, pitted
4 hard-boiled eggs, peeled and thinly sliced

Directions

Put onions, 1/4 cup oil, vinegar, and 1/4 teaspoon salt in a medium bowl; season with pepper. Toss to combine. Let stand 10 minutes.
Add tuna and its oil to onion mixture. Add lemon juice and 1/4 teaspoon salt; season with pepper. Gently toss to combine.
Cover bottom halves of rolls with lettuce. Top with olives, eggs, and tuna mixture, dividing evenly. Drizzle each with 1 teaspoon olive oil. Cover with top halves of rolls. Serve with lemon wedges.

Cook's Notes

Because tuna is the star ingredient in this sandwich, it's worthbuying oil-packed tuna in a jar, which has a higher qualityand finer flavor than the canned variety.
