There was a thing on tv the other day about how it's genetic whether we like sprouts, which I'm guessing applies to all green veg! Apparently they taste more bitter to some people!
It sounds weird, but have you tried roasting them? The flavour is totally different! I'm a big green veg fan though, I was telling the kids yesterday how I used to have everyone's sprouts at school Xmas dinner

I still love them now!
