Preheat oven to 200c or 400f (gas mark 6)
Add some avocado oil to frying pan over a medium heat.
Add the onion and fry for a few minutes till translucent.
Add the carrot and garlic and fry for a further few mins.
Add to a bowl the potatoes, zucchini, cheddar, eggs, tapioca starch and sauteed onion, carrot and garlic.
Season with a little black pepper.
Mix all together with a spatula.
Line a baking tray with parchment paper, and roughly form the mixture into 12 equal sized patties and place on the tray (mixture will be quite wet, but will firm together when cooked)
