STEP 1

Finely chop the garlic. Heat the oil in a large pan and fry the onion, stirring frequently, for 8 mins. Stir in the balsamic vinegar and cook for 2 mins more. Meanwhile, put the beans in a bowl with the egg, tomato purée and spices, and mash until smooth. Stir in the almonds and sweetcorn with the thyme, a third of the chopped garlic and the balsamic onions. Mix well and shape into about 8 balls the size of a walnut, and place on a baking tray lined with oiled baking parchment.
