We start by filling a baguette with green beans, tuna, olives, herbs, vinaigrette, and peppers. Then we wrap up the entire baguette and press until the flavors meld and the sandwich bursts with flavor. Because this sandwich needs at least an hour to marinate, it’s perfect for packing in picnic baskets, backpacks, or lunch bags. Shopping tip: Look for vibrant, plump green beans that are still crisp, since you’ll be eating them raw. Ingredients 1 baguette (about 16-inches long) ½ cup plus 1 tablespoon olive oil, divided 1 cup loosely packed fresh basil leaves, torn ¼ cup red wine vinegar 1 tablespoon Dijon mustard ¼ teaspoon kosher salt ¼ teaspoon freshly ground black pepper 1 small red onion, thinly sliced 1 (6-oz can) solid white tuna in spring water, drained and flaked 6 ounces green beans, trimmed and halved crosswise ¾ cup pitted Niçoise olives, coarsely chopped ½ cup roasted red peppers, torn if large ½ cup packed fresh flat-leaf parsley leaves and tender stems Directions Slice baguette in half lengthwise without cutting all the way through. Brush the bottom half with 1 tablespoon oil and arrange basil leaves on top. Set aside. Whisk vinegar, mustard, salt, and black pepper in a large bowl. Add onion and toss to combine. Set aside to marinate, about 10 minutes. Remove onion from bowl and arrange on top of basil. Reserve vinegar mixture. Slowly whisk the remaining ½ cup oil into the vinegar mixture. Add tuna, green beans, and olives. Toss and then add the mixture to the baguette. Top with red peppers and parsley, and then close the baguette. Wrap baguette tightly with plastic wrap and place between two baking sheets. Place a heavy skillet on the top baking sheet to compress. Chill, pressed, for between 1 and 4 hours. Unwrap and slice crosswise into 4 sandwiches. A classic salad plus the flavor-enhancing technique of a Muffuletta. A crunchy baguette gets stuffed with lightly-dressed tuna, green beans, olives, herbs, roasted red peppers, and onion. Wrapping it in plastic and placing weight on the sandwich allows for the flavors to meld. A breeze to transport, just slice up at your destination. Get the recipe: Tuna Niçoise Baguette.
