Failing all else try some bribery and corruption.

Offer him a small treat if he will try some new vegetables at a meal from time to time.
The old carrot-and-stick approach (sorry, no pun intended). My sister-in-law does this with her two (aged 9 and 7). If they've been good all week and eaten everything, it's amazing what treats might come their way, and these are of course nothing compared to the dire consequences of not having had so much as a single pea in the course of a week. Mind you, the children's idea of a treat or a punishment doesn't match mine - how simple life was when an extra Yorkshire pudding was all I wanted in life!
I seem to remember reading that it can take up to nine attempts for children to actually like something, and I mean actually trying the food, not just looking at it and deciding they don't like it, so don't give up!
Try to make the vegetables exciting as well. I'm sure I'd be more into veg than I am if my mum hadn't cooked the vegetables to within an inch of their life (although not quite like the cauliflower about which I once heard which had had 30 minutes in a pressure cooker

).
