Preheat oven to 350F
Grease or line a baking pan
Grate zucchini, drain excess liquid using paper towels, mesh strainer or a cheesecloth
In a medium bowl, add in sifted flour and baking powder and mix to combine.
In a large bowl, whisk the eggs with salt and pepper (you can also add 1/2 tsp onion powder and 1/2 tsp garlic powder for additional flavor, but the classic Australian recipe just calls for salt and pepper)
Stir in zucchini and oil then the flour baking powder mixture. Next mix in the chopped onion, bacon, and cheese.
Pour mixture into prepared baking dish.
Bake for 30 minutes or until golden brown and cooked through.(skewer should come out clean). Enjoy!
