Cut your tomato into slices. Slice the breads in half lengthwise to create top and bottom halves, leaving you with two pieces of each, ready to fill.
1 Tomato, 4 Panini Bread
Spread 1 Tablespoon of pesto over each bottom half.
4 Tablespoon Pesto
Break or cut your cheese slice into two and place the cheese rectangulars over the pesto.
4 Slices Cheese
Place two to three tomato slices over the cheese and sprinkle some salt over the tomatoes. Close the panini with the top half.
1 Tomato, Pinch Salt
Place the panini into a panini press and press down. OR keep a pan with the panini on the heated stove top and press down with another pan or any other flat and clean cooking object, and then turn the panini to toast on the other side as well.
Serve hot with your favorite dipping sauce and side salad.
