A delightful Mediterranean-inspired sandwich filled with a flavorful tuna salad and fresh vegetables.
Combine the lettuce, tuna, red onion, and capers in a medium bowl.
Ensure the tuna is well-drained to avoid excess moisture in the salad.
In a small jar, mix olive oil, minced garlic, oregano, black pepper, and salt. Shake well to combine.
You can use a whisk if you don't have a jar with a lid.
Pour the dressing over the salad mixture and toss to coat evenly.
Toss gently to avoid bruising the lettuce.
Slice the baguette lengthwise and open it up.
You can lightly toast the bread for added texture.
Layer the bottom half of the baguette with tomato slices, then add the salad mixture on top.
Spread the salad mixture evenly for consistent flavor in each bite.
Close the baguette, wrap it tightly in plastic wrap, and refrigerate for at least 1 hour.
Chilling helps the flavors meld together for a more cohesive taste.
Slice the sandwich into portions and serve.
Use a sharp knife to ensure clean cuts through the sandwich.
