- Heat the oil in a frying pan over a medium heat. Cook the onions for 5 mins, then reduce the heat to low and add a splash of water. Cook for 30 mins, stirring regularly, until soft and caramelised.
- Increase the heat to medium and stir in the sugar and vinegar. Cook for 3 mins or until sticky and glossy. Remove from the heat and set aside to cool a little.
- Meanwhile, lightly toast the bread, then spread with butter. Mix the cooled onions with the grated cheese and herbs and scatter evenly over the toast. Grill for 5 mins or until melted and lightly golden; add a crack of black pepper and serve with rocket, if you like.
