Ingredients
3/4 cup pitted and chopped kalamata olives
2 tablespoons olive oil
2 garlic cloves
1 teaspoon lemon zest
1/4 cup mayonnaise
2 (6-ounce) cans tuna in olive oil, drained
1 (12-ounce) jar marinated artichokes, drained and coarsely chopped
1 teaspoon fresh lemon juice
1/2 teaspoon freshly ground black pepper
1 (16-ounce) ciabatta bread, halved horizontally
1 tomato, diced

Instructions
Puree the olives, oil, garlic, and zest in a food processor until smooth and spreadable. Blend in the mayonnaise. Toss the tuna, artichokes, lemon juice, and pepper in a medium bowl, keeping the tuna in small chunks.

Spread the olive puree over both cut sides of the bread. Spoon the tuna and artichoke mixture onto the bottom half of the bread. Sprinkle the tomatoes over. Cover with the bread top. Grill on Panini Press.
