Preheat your griddle over a medium flame. (If necessary, first spray with non-stick cooking spray or rub with a few drops of olive oil.)
Beat the crust ingredients until smooth.
Wait until the griddle is hot enough (when drops of water sizzle up).
Spread your batter into a circle (about 10 inches, 25cm diameter).
After a couple of minutes, flip over.
Remove from heat.
Line your broiler tray with foil, and place crust on top.
Top with tomato sauce, grated cheese, and mozzarella.
Broil for a few minutes, until cheese is melted to your liking.
Remove from broiler, and enjoy!
