How to Make It
In a large wide saucepan heat the olive oil and butter and gently cook the onion on low until soft. Add the garlic and cook for 2 more minutes. Turn the heat up to medium and add the rice stir constantly for 30 seconds to coat the rice.
Over a medium heat add the stock in about 8 increments allowing for each addition to be absorbed before pouring in more.
When you have about 150ml left add the vegetables, remaining stock, butter, Parmesan and 1/2 tsp ground black pepper and turn off the heat. Stir once and put a lid on it and set aside to rest for 10 minutes. When that time is up spoon the mixture into a bowl or wide plate and leave to cool.
Heat the sunflower oil in a small shallow frying pan on medium. Divide the cold mixture into 16 and shape into small cakes. Put the flour and breadcrumbs onto separate plates and beat the eggs in a shallow bowl.
Dredge each rice cake in the flour then into the eggs and finally into the breadcrumbs. You can also prepare the cakes in advance and keep in the fridge for up to a day and fry when needed. Fry the cakes a couple at a time for 2 minutes on each side until they are completely piping hot throughout and drain on a plate with kitchen towel. Squeeze over juice from the lime and serve immediately.
