Pat the chickpeas dry with kitchen paper. Tip into a food processor along with the onion, garlic, parsley, spices, flour and a little salt. Blend until fairly smooth, then shape into four patties with your hands.
Heat the oil in a non-stick frying pan, add the burgers, then quickly fry for 3 mins on each side until lightly golden. Serve with toasted pittas, tomato salsa and a green salad.
