A delightful Mediterranean-inspired sandwich featuring tuna, fresh vegetables, and a tangy dressing, all nestled in a crusty baguette.
Combine the diced tomatoes, olives, and salt in a bowl and let them sit for 15 minutes to release their juices.
Letting the tomatoes sit with the salt enhances their natural flavors and creates a delicious base for the sandwich.
Slice the baguette lengthwise, leaving one side attached, and remove some of the soft bread from the center.
Removing some of the bread from the center creates space for the filling and prevents the sandwich from becoming too bulky.
Brush the inside of the baguette with olive oil and spread the tomato mixture evenly inside.
Using a brush ensures an even coating of olive oil, which adds flavor and prevents the bread from becoming soggy.
Layer the onion slices, green pepper slices, and tuna over the tomato mixture.
Arrange the layers evenly to ensure each bite has a balance of flavors.
Whisk together the vinegar, minced garlic, anchovy paste, and remaining olive oil, then drizzle over the filling.
Drizzling the dressing evenly ensures every bite is flavorful and moist.
Wrap the sandwich tightly in plastic wrap, place a heavy skillet on top, and let it rest for 30 minutes to allow the flavors to meld.
Pressing the sandwich helps the flavors meld together and makes it easier to eat.
Unwrap the sandwich, slice it diagonally into portions, and serve.
Diagonal slices make the sandwich easier to handle and more visually appealing.
