I try this from time to time with Jessica Seinfeld's cookbook
Deceptively Delicious. I think it's all good but when you cook the
veggies twice for her recipes (purees and then into food), I do
think you lose most of the nutritional value.
My nutritionist says kids have to try foods 25 times to accept
them. I have noticed that this has worked.
Personally, I'd do both.
