How to make
For the walnut pesto, blend the walnuts, garlic, olive oil and basil with a pinch of salt in a blender or food processor. Once you get a homogeneous mixture, mix the grated parmesan in.
Cut the tomatoes and mozzarella into thin slices and arrange them in a large plate, alternating them. Cover with walnut pesto on top, garnish with a sprig of basil and serve.
