Grate the zucchini and squeeze to drain the moisture. Mix all the ingredients in a blender, except for the zucchini. Fold the zucchini into the egg mixture. Pour into a buttered 10 inch pie plate or quiche pan. Bake in a 350 Fahrenheit oven until filling is browned and knife inserted comes out clean, about 35 to 40 minutes. You may add grated cheddar cheese and garnish with a little extra fresh oregano.
