Prepare the Ingredients:

If you’re using a loaf of ciabatta or focaccia, slice it into individual portions and then slice each horizontally to open up for the sandwich.

Assemble the Sandwich:

Spread 1 tablespoon of basil pesto on the inside of each bread half.

On the bottom halves, layer the turkey slices, cheese, and a few leaves of spinach or arugula, and tomato slices if using.

Top with the other half of the bread.

Heat the Panini Press:

Preheat your Panini press. If you don’t have a Panini press, you can use a heavy skillet or grill pan.

Brush the outside of the sandwich lightly with olive oil or butter. This will help to get a nice, crispy, golden crust.

Grill the Panini:

Place the sandwich in the Panini press and close it. Grill for about 4 to 5 minutes or until the bread is toasted and crispy and the cheese has melted.

If using a skillet, place the sandwich in the skillet and press down with another heavy pan or a spatula. Grill each side for about 3 minutes.
