📖 Instructions

1. Drain the Tuna: Open the cans of tuna and drain them well. Flake the tuna into a medium-sized mixing bowl. Get rid of as much water as possible. Nobody wants a wet sandwich!
2. Chop the Vegetables: Finely chop the red onion, celery, and sun-dried tomatoes. The smaller the pieces, the better they'll blend into the salad. Aim for roughly the same size, about 1/4 inch. Add them to the bowl with the tuna.
3. Add the Briny Goodness: Add the Kalamata olives (halved or quartered if large), capers, and fresh parsley to the bowl. These ingredients provide that essential Mediterranean flavor. If you don't have Kalamata olives, feel free to substitute with another type of olive, but Kalamata really makes a difference.
4. Make the Dressing: In a small bowl, whisk together the olive oil, lemon juice, Dijon mustard, salt, and black pepper. Taste and adjust seasonings as needed. The dressing should be bright and flavorful. Start with 1/4 teaspoon of salt and add more to taste. Some capers and olives can be very salty, so be cautious!
5. Combine Everything: Pour the dressing over the tuna and vegetables. Gently stir everything together until well combined. Be careful not to overmix, as you want the tuna to maintain some texture. The mixture should be moist but not swimming in dressing. Remember the goal: Tasty tuna sandwich!
6. Toast the Bread: Lightly toast the slices of bread. This adds a nice crunch and prevents the sandwich from becoming soggy. I prefer a crusty bread like ciabatta or sourdough for this recipe, but any sturdy bread will work. Watch carefully to avoid burning. Keep an eye on it like a hawk!
7. Assemble the Sandwich: Spread a thin layer of mayonnaise (optional, but adds creaminess) on one or both slices of toasted bread. Pile the Mediterranean tuna salad on one slice of bread and top with the other slice. If you want to make it extra fancy, add a few leaves of fresh arugula or lettuce.
8. Cut and Serve: Cut the sandwich in half and serve immediately. Enjoy with a side of chips, a salad, or your favorite Mediterranean-inspired sides. I personally love it with a simple Greek salad. I find it very refreshing
