You could make these patties bite-size for a vegetarian canapé, or simply one large one – like a frittata with a twist.
Combine all the ingredients except the oils in a large bowl with some seasoning and mix well. Heat both the oils in a frying pan. Grease an 8cm metal pastry ring or cookie cutter and place in the pan. When hot, pour 5 tbsp of the batter in and turn the heat down to medium.
Cook 4-5 mins until golden, then take off the ring (be careful, as it may be hot), flip the pattie and cook the other side. Do this in batches, keeping finished patties warm in a low oven. Serve with the chilli sauce and extra spring onions, if you like.
