Prepare a baking sheet with parchment paper and place a tablespoon or so of almond flour in the center of the sheet where the dough will go.
Shred the zucchini in a food processor with a shredding attachment, or shred by hand using a vegetable grater. Drain any excess liquid.
Combine the almond flour, salt, oregano, and garlic powder in a bowl and whisk to blend.
Add the eggs and zucchini to the bowl and blend all the ingredients into a wet dough. If there's excess liquid add an extra tablespoon or so of almond flour to thicken it.
Scoop out about half the dough onto the almond flour area on the baking sheet and shape the dough with the back of a spoon or spatula so you have a round pie, about six to eight inches in diameter.
Bake the crust for 15 minutes or until the edges are browned and the center is firm.
Cool for a minute and then add toppings. Lower the oven temperature to 400℉ and bake for another 10 minutes or so. (If you're making the cherry tomato topping (recipe below), bake it before adding it to this step).
Serve warm. Store leftovers in the refrigerator for a few days, or freeze for a few months.
