Rinse the sushi rice under cold water until the water runs clear. Combine the rice and water in a rice cooker and cook according to the manufacturer's instructions.

Once cooked, transfer the rice to a mixing bowl. In a small bowl, mix rice vinegar, sugar, and salt until dissolved, then fold this mixture into the rice gently.

Place a sheet of plastic wrap on the sushi mat. Spread a thin layer of sushi rice over the plastic wrap, leaving a small border at the top.

Layer the mozzarella, prosciutto, roasted red peppers, and basil on top of the rice.

Using the sushi mat, carefully roll the sushi away from you, pressing gently to form a tight roll. Seal the edge with a little water.

Using a sharp knife, slice the sushi roll into bite-sized pieces. Wipe the knife with a damp cloth between cuts to ensure clean slices.

Serve the Italian sushi with a dipping sauce made from balsamic vinegar, olive oil, and Italian herbs.
