Clean the zucchini and cut off the ends. Shred the zucchini into a large mixing bowl. You can peel the zucchini skin if you wish or leave it on. Add the salt to the zucchini and toss to combine. Set aside for 10 minutes to draw the moisture from the zucchini. Give it a good squeeze with your hands and drain away any excess liquid.
Add the coconut flour, cheese, Italian seasoning and pepper to the mixing bowl. Stir well to combine. The mixture should start to clump together.
Crack the egg into the bowl. Beat well into the mixture. The mixture should now be holding together like a dough.
Preheat the oven to 400 degrees Fahrenheit and line a large shallow oven tray with baking paper. Turn the dough out onto the lined oven tray. Press gently into a large circle. This should be about 1/4 inch thick.
Transfer the zucchini pizza base to the oven to bake for 20 minutes. Remove and top with your favorite pizza sauce and toppings. Return to the oven to bake for a further 10 minutes or until the pizza base is golden and the toppings are cooked through.
