For the vegetable patties: Put the grated courgettes and aubergine in a colander, sprinkle with salt and leave to drain for 10’. Squeeze out all the excess moisture and transfer to a bowl. Add all the remaining ingredients except the flour and stir together well.
Lastly mix in the flour to form a dough and shape into large patties. Add a little more flour if necessary. Dust the patties in flour and shake off any excess. Fry in olive oil until golden brown on both sides. Drain on kitchen paper. (Or, arrange the patties on a greaseproof paper-lined baking tray and bake in the oven for 15’ at 200 degrees C).
Serve the vegetable patties hot, or cold with yogurt dip with spearmint.
