Mashed aubergine salad ???

Another aubergine (egg plant) recipe? You must think I am mad. Yes, every week when I go shopping if I see aubergines on offer I must bring some home. I bought four yesterday. I wanted to use half straight away because of limited fridge space and the other half later in the week.So what tickle my tastebuds this time? I want something guilt free (reasonably low fat), easy to make and tasty.
