Best 2 Tuna Nicoise Sandwich Recipes

NIçOISE TUNA SANDWICH (PAN BAGNAT)

Steps:

• Combine the red and white onion with 2 tablespoons extra-virgin olive oil,1 tablespoon red-wine vinegar, 1/4 teaspoon salt, and several grinds of black pepper in a bowl.
• Using your hands, mix and squeeze everything together for 5 minutes. (Don't rush through this part; the onions need time to release their juices and mellow.)
• Work in can of tuna in olive oil, including the oil. Season with fresh lemon juice, red-wine vinegar, and salt, then add pepper to taste.
• Cut kaiser rolls in half crosswise and spread each bottom half with lettuce leaves. Use a couple of varieties-whatever looks good-for the difference in texture.
• On top of each lettuce layer, arrange 4 tomato slices (skip this step if you don't have good-really good-tomatoes on hand). Then add about half the tuna mixture and 3 to 4 slices of hard-boiled egg.
• Crisscross each sandwich with 2 drained anchovy fillets and strew with Niçoise olives (pit them if desired), chopped scallion greens, and sliced radishes. Then drizzle generously with more olive oil and top with the remaining kaiser halves, pressing gently but firmly.

TUNA NICOISE SANDWICH

Steps:

• For the White Bean Puree: Soak the beans overnight. Or place beans in a pot, cover with cold water and bring to a boil over high heat; remove from heat and set aside, covered, for 1 hour. Drain the beans; transfer to a 2-quart pot with the diced onion, smashed garlic, bay leaf, thyme sprigs, 5 cups of stock, and salt and pepper, to taste. Bring to a boil. Lower the heat; simmer until beans are very tender and are breaking apart, about 2 hours. If the mixture becomes dry, add some of the remaining stock. Drain the beans; discard the thyme sprigs and bay leaf. Puree the beans in a food processor, adding a few drops of oil. Adjust seasonings with salt and pepper, to taste, along with the lemon juice, white vinegar, and walnut oil, if desired. Reserve.
• For the Olive Tapenade: In a food processor or mortar, combine the olives, capers, lemon zest, garlic, parsley, and salt and pepper, to taste. Slowly add the oil and pulse or work with the pestle into a coarse paste, retaining some bits of olive and caper for texture. Taste to adjust the seasonings. Reserve.
• Sandwich Assembly: Smear with white bean puree on 4 pieces of potato bread. Arrange sliced tuna on top. Drizzle tapenade over tuna. Add sliced tomatoes, sliced egg and dressed French green beans. Top with greens and toasted bread. Garnish with basil and arugula.
