Add 1 tbsp of olive oil to a shallow, wide-bottomed casserole pan and set over a medium heat. Once hot, add 2 chopped aubergines and cook for around 8 minutes, stirring often, or until the aubergine is golden all over. You can add a splash more oil here, or a little water if you want if the aubergine are looking dry. They are sponges so can soak up too much oil so you need to be careful but you don't want them dry. It depends slightly on the size of the aubergine. Remove from the pan and tip into a bowl. Set aside.
