What do you put in your chilli con carne?

I'm Australian. I've been told before that my mum's version is weird because she puts capsicum and kidney beans in it and serves it with white rice and Greek yoghurt.

I was fancying it last night and instead of taking another trip to the supermarket, I put in what I had (capsicum, mushroom, zucchini, chickpeas, onion, and mixed beef and pork mince). It still tasted like chilli, but I had the vague impression that it was incorrect to call it that.
