Finely grate onion, carrot and zucchini.
Cook chickpeas until they are soft, then strain. Cook and strain quinoa also, making sure it isn't overcooked. If it's too soft the burgers will be a bit sloppy.
Finely dice the coriander.
In a food processor add chickpeas and quinoa. Blend until the chickpeas are a combination of chunky and smooth.
Place all ingredients into a large bowl. Mix all ingredients well to combine.
Heat a frying pan until it is hot, then lower to medium heat. Add butter, ghee or coconut oil to the pan.
Form a large ball with the burger mixture in your hands, then press them down flat in the frying pan with an egg flip. Alternatively you can press the mixture into a metal egg ring to form a perfect shape.
When the burgers are brown, carefully turn them over.
Serve warm with your favourite sides and toppings; pesto, homemade mayonnaise, beetroot hommus, cashew cheese, sauerkraut, salad.
