Ingredients
  

  • 1 8-ounce jar sun-dried tomatoes packed in olive oil drained (reserve the oil)
  • Zest and juice of 2 lemons
  • ½ cup fresh basil leaves chopped
  • 2 tablespoons chopped fresh dill
  • Kosher salt and freshly ground pepper to taste
  • Pinch of crushed red pepper flakes
  • 1 loaf focaccia bread halved lengthwise
  • 2 5-ounce cans oil-packed tuna drained
  • ¼ cup pitted kalamata olives chopped
  • 1 roasted red pepper chopped
  • 2 cups fresh arugula
  • 4–6 ounces feta cheese crumbled

Instructions
 

  • Prepare the Dressing: In a small bowl, whisk together the reserved olive oil, lemon zest, lemon juice, chopped basil, and dill. Season with kosher salt, freshly ground pepper, and a pinch of red pepper flakes. Use a spoon to drizzle and spread this mixture on the cut sides of the focaccia bread.
  • Chop Ingredients: Roughly chop the sun-dried tomatoes.
  • Assemble the Filling: In a medium bowl, combine the tuna, kalamata olives, roasted red pepper, and chopped sun-dried tomatoes. Stir to mix well. Spread the mixture evenly over the bottom half of the focaccia bread.
  • Add Freshness: Layer arugula on top of the tuna mixture, then sprinkle crumbled feta cheese over it.
  • Finish the Sandwich: Place the top half of the focaccia bread over the filling and press gently. Slice the assembled sandwich into four equal pieces.
  • Storage Option: Wrap sandwiches individually in plastic wrap and store in the refrigerator for up to 1 day for convenience.

Notes

Substitution: Ciabatta bread can be used as an alternative to focaccia, as it holds up well and does not get soggy.
Make Ahead: This sandwich can be prepared the night before, making it an excellent option for on-the-go lunches or quick dinners.
