Separate the egg whites from the yolk and set the yolk aside. In a stand mixer or with an electric whisk, whisk the egg whites. Add in the lemon juice and continue whisking until stiff peaks form. Set aside.
In a medium bowl, whisk together the egg yolk and cream cheese until smooth.
Mix the egg whites into the egg yolk and cream cheese, adding the whites 1/3 at a time. Try not to over-mix as this will deflate the egg whites. Transfer the mixture onto a prepared baking sheet and gently spread to form a roughly 8-inch circle.
Bake for 20-25 minutes. For a crispier base, bake for an additional 5-10 minutes. Cool for a few minutes on the baking sheet before proceeding with the pizza toppings.
As the cloud bread cools, increase the oven temperature to 180°C (356°F).
Assemble the pizza
In a small bowl, mix the passata and seasonings. Pour the passata onto the cloud bread base, top with light cheese and any additional toppings. Bake for 10 minutes, cool for a few minutes on the baking sheet before serving. Enjoy!

Notes
Beat until super stiff - The egg whites need to be really firm in order for the cloud bread to bake. Under-beating the egg whites will lead to a flat and sloppy base so keep whisking until stiff peaks form!Don't over-mix - When folding the whipped egg whites into the egg yolk and cream cheese, make sure not to over-mix. This can deflate the egg whites and lead to a flat base.Season the passata - Typically, the egg yolk and cream cheese mixture is seasoned to give the cloud bread some flavor. I prefer to season the passata instead as it packs more of a punch this way!
How to serve and store the best low calorie pizza
You can make one mini pizza and enjoy it as a snack. I also like to have a few of these low calorie pizza's for dinner. It is high in protein and fairly light.These low calorie pizzas are best served the day they are made. However, if you want to make ahead and store, the best way to do so is by freezing. Bake the cloud bread and allow to cool. Add the toppings and freeze. You can bake the frozen pizza at 180°C for 15 minutes.
