A non-stick grill pan is preferred but a non-stick skillet will work fine.
Four Slices Of Ciabatta Bread About One Inch Thick
Four Slices Of Fresh Tomato About 1/2 Inch Thick
Four Slices Of Fresh Mozzarella About 1/2 Inch Thick
A Tablespoon Of Chopped Fresh Basil
1/2 Teaspoon Of Sea Salt
1/8 Teaspoon Of Ground Black Pepper
A Tablespoon Of Olive Oil
Heat the grill pan on the stovetop on medium heat for 4 minutes.
Place two slices of tomato on a slice of ciabatta bread. Sprinkle the tomatoes with sea salt and ground black pepper. Place half of the basil on top of the tomatoes. Place one mozzarella slice on each tomato. Place a slice of ciabatta bread on top of the mozzarella slices. Brush both sides of the sandwich with olive oil. To make the second sandwich, repeat the same process.
Put the sandwiches on the grill pan. Put a heavy pan or pot on each sandwich to press it down. Cook for about three minutes on each side or until golden brown and the cheese has melted.
Cut the panini sandwiches in half and serve.
