Kerryn, great tip.
My kids are great with veg in general (they tend towards the vegetarian) but dd3 can be fussy sometimes (though at the moment veg is her best friend) but still love being able to throw a larger variety into something hidden. (eg dd2 won't eat mushroom or onion if in chunks, none of them love zuchinni as a side, though they are all eating bucketfuls of capsicum at the moment) . Will def try that when we have pizza this week.
