It was pretty good. I found the recipe long time ago and few of my friends had tried it and said it was nice so I gave it a go. I don't need to have gluten free food so this was just experiment as I was going to make omelette for dinner but remembered the recipe and decided finally to try it so that's why I didn't use gluten free flour.
So its really simple. You need 5 eggs. Separate the yolks from whites, break the yolks and add some salt in then whisk the whites to soft peak and mix the two gently. 200C for 15 mins, then add your toppings and cook another 15 to 20 mins.
Only thing was that it was quite moist, so less toppings would have been better or maybe cooking the base more I'm not sure. Didn't taste like egg at all, pretty close to normal pizza and at 337 calories for half of the pizza it suits my diet well..
