Turn your grill on high.

Line a tray with foil and rub with a little oil. Place your slice of tofu on the tray and grill for about 2 minutes or until starting to brown. Or if you have more patience, until it is golden brown.

Meanwhile combine egg and parmesan in a small bowl.

Flip the tofu so the brown side is on the bottom. Spread a thin layer of miso paste or vegemite (if using) onto the surface of the tofu or scatter generously with salt. Spoon the eggy parmesan mixture over the top to cover most of the surface of the tofu.

Return to the grill and cook for another 2 minutes or until the cheese mixture is puffed and deeply golden brown.

Serve hot with pickles or salad on the side.
