No one knows Nutella like the Italians, which is why this panino recipe perfectly harmonizes the the national ingredient into a favorite staple.
Pre-heat an electric panino machine to 300 degrees or heat a cast-iron grill pan to medium.
Place the slices of ciabatta onto a clean surface. Evenly distribute and spread the Nutella onto 2 slices of the ciabatta. Place the remaining 2 slices on top.
Place one of the Nutella filled panini at a five o'clock position onto the pre-heated electric panino machine or the pre-heated cast-iron grill. Cook until grill marks have formed, about 2-3 minutes, and then rotate to the seven o'clock position and continue to grill. Once the grill marks are clearly evident on both sides, another 2-3 minutes, transfer the grilled panini to a clean cutting surface. Utilizing a clean serrated knife, carefully cut each of the panini into 6 equal pieces. Arrange the 6 slices onto a plate and dust with confectioner's sugar and serve at once.
