In a large mixing bowl, combine all the dry ingredients. Make a well in the center and add beaten eggs and olive oil.
Combine with a spatula at first, then use your hands to form a ball of pizza dough.
Place the dough ball between two parchment paper pieces and roughly press the ball with your hands to flatten it into a thick disc.
Start rolling with a rolling pin until it forms a 12-inch (30 cm) diameter pizza crust (for an ultra-thin crust) or roll into a 10-inch (25 cm) pizza crust for a slightly thicker crust.
Peel off the top piece of parchment paper, smoothen the sides of the pizza crust to make it pretty, then slide the bottom parchment paper piece (with the rolled pizza dough on it) onto a baking tray.
Prebake the crust for 10-12 minutes or until golden and crispy. The thicker you roll it, the longer it takes to crisp.
Remove from the oven, spread a thin layer of unsweetened tomato passata, and toppings of your choice. Note that any vegetable that releases a large amount of water would soften the center of the dough. This includes mushrooms, tomato slices, eggplant, or zucchini. If you want to use those vegetables, I recommend pre-roasting them 8 minutes in the oven to avoid them to release water on your pizza base.
Return pizza into the oven and bake in the center rack of the oven until cheese is melted. You can broil the cheese on the top rack for 2-3 minutes, but it will significantly darken the sides of the pizza. To avoid this, you can protect the pizza sides with pieces of foil.
Serve immediately into 8 slices.
Freeze the leftover baked pizza slices individually, in silicone bags or airtight containers. Defrost 2 hours before on the counter then bake at 160°C (320°F) for 5-8 minutes or until warm.
Vegan option: note that the result will be very different. It will be less crispy and slightly more fragile to roll. For a two-egg replacer in the recipe, combine 2 tablespoons of flaxseed meal (or ground chia seeds) with 6 tablespoons of lukewarm water. Stir well, set aside 10 minutes until it looks like eggs in texture. Use in the recipe as an egg replacer.
