We have a similar issue here too and I've resorted to having fruit on his plate as well as his veg and meat or whatever we are having that night. That way DS gets his fruit and he'll eat some of the other food too instead of waiting for me to cave in and just give him some fruit if he hasn't eaten anything else.
A health nurse told me once to put 2 or 3 peas/corn vegies on his plate and very small amounts of whatever else we were eating plus a quater of a sandwich and if he ate the sandwich 1st then all he needed to have was the couple of vegies and that would be ok.She also told me that sometimes smaller amounts is more appealing to little tummies instead of larger amounts kwim?
