Step 1: Prepare the Bread : Lay out the bread slices on a clean surface. Spread about 1 tablespoon of pesto on each slice (adjust according to taste).
Step 2: Assemble the Panini : On two slices, layer fresh mozzarella slices evenly. Add tomato slices over the mozzarella. Sprinkle a little salt and pepper over the tomatoes. (Optional) Add fresh basil leaves or a drizzle of balsamic glaze for extra flavor. Place the remaining two bread slices on top, pesto side facing down.
Step 3: Grill the Panini : Preheat your panini press, grill pan, or skillet over medium heat. Lightly brush the outer sides of the sandwiches with olive oil or butter.
Place the sandwiches on the hot surface. If using a panini press, close the lid and cook for 4–5 minutes until golden and crisp. If using a skillet, press down gently with a spatula or another pan and cook 3–4 minutes per side, until the bread is toasted and cheese is melted.
Step 4: Serve and Enjoy : Remove from heat and let rest for a minute before slicing. Cut each panini diagonally and serve warm with your favorite sides.
