Steer clear of kiwi fruit, Soozie - they're nappy armageddon. And all of my kids have had very sore bums at some time as a result of being allowed to feed freely on grapes.
What worked for me was to get myself a big plate of fruit or vegetables and tell the sprog-of-the-moment that it was mine, not theirs. That soon had them positively begging! I'm trying the same thing now (with limited success) to get numbers 3 and 4 to eat recognisable meat instead of fish fingers and chicken nuggets.
