Egg whites, cottage cheese, flaxseed flour and italian spices. DON'T EVEN THINK ABOUT ADDING BAKING SODA.
Baked the pie at 350F for over 20 minutes (closer to 30?), covered with aluminum foil, then topped it with usual pizza toppings and baked it at 400F for almost 20 (until cheese started browning).
Will need to bake the crust longer next time, so it's firmer and darker.
