This Caramelised Red Onion & Aubergine (Eggplant) Dip is a tasty and easy summer dip that has child appeal with the sweet flavour of red onion, and is fairly budget with the use of canned kidney beans to add thickness and texture. It's also gluten free. I came up with this recipe basically because I needed to use up an aubergine, and being a lazy cook at times, one of my favourite ways of cooking aubergine is to blast the whole thing in the microwave.
I don't use the microwave that often in my cooking, but preparing an aubergine like this - with the skin intact - is one of the simplest ways of using aubergine for recipes. It means the inside goes all soft and is very versatile for dips or sauces, but you also get to retain the skin, which doesn't char.
