My oldest used to eat anything, now he's completely unpredictable, and pretty difficult when it comes to vegetables. So I went to my pile of Practical Parenting magazines, and found a recipe for hidden vegetable tomato sauce. I can't print the recipe, as I assume that it's covered by copyright.
The principle is to chop up the vegetables finely and then puree the sauce after it's done. That way it looks like a plain tomato sauce, and the child is none the wiser. It worked for us. Instead of chopping, I blitzed the vegetables, and I used a can of chopped tomatoes instead of the tomato passata. When it had finished cooking, I think I could have gotten away with serving it as is, as it looked unthreatening, but I didn't take any chances, and went ahead and pureed it.
It certainly made for a much more tasty tomato sauce than the one I usually make, and both kids devoured it.
