Pour oil into a pan and caramelize the onions then add the crushed garlic and fry it until it gets fragrant. (Check out the Low Carb Condiments for detailed Tomato Sauce recipe)
Pour the pureed tomato and add basil, oregano and salt then cook it on low heat until about quarter of the liquid evaporates. Add salt to taste.
Pizza base
Slice up the eggplants to desired width. Our favorite is the fine pizza crust that is 0.1" / 3mm thick. Place the sliced up eggplants onto a parchment papered baking tray and sprinkle some salt on top.
Let the salt drive out some moisture for 10 - 15 minutes.
Place the eggplants into a 480°F / 250°C preheated oven for 10 minutes to pre-bake them. It's an optional step if we want to get rid of the eggplant flavor for a more pizza like experience. Optionally we can also fry the eggplants in a frying pan.
Topping
Grate the cheese and cut the necessary ingredients up.
Assembly
Spread pizza sauce on top of the eggplants then sprinkle cheese and any additional ingredients.
Place the pizza onto the top shelf of a 480°F / 250°C preheated oven until the cheese gets golden brown for about 8 - 10 minutes.
