Italian Tuna Panini

• Recipe by Giuseppe Forte

Ingredients

1. Two 6-ounce cans Italian tuna packed in olive oil, drained
2. 3 tablespoons fresh lemon juice
3. Salt and freshly ground pepper
4. 1/4 cup extra-virgin olive oil
5. 8 slices firm white sandwich bread or 4 ciabatta rolls, halved lengthwise
6. 1 medium onion, thinly sliced

Directions

1. In a small bowl, combine the tuna with the lemon juice and season with salt and pepper. Brush the olive oil on the bread or ciabatta. Spread the tuna on 4 slices of the bread and top with onion slices. Close the panini.
2. Set a large cast-iron skillet or griddle over moderately high heat. Arrange the panini in the skillet and weight them down with a smaller pan. Cook the panini until the outside is crisp and the filling is heated through, 1 to 2 minutes per side. Cut the panini in half and serve at once.
