As we already learned, the taste bud factor is a big one when trying to get your little ones eating their vegetables, so is it really such a big deal if you have to disguise their veggies to get them to eat them? I have never found this to be a problem. At the end of the day you are expanding their world of food, and they are still getting the important vitamins and nutrition.
Upon serving a particular pasta dish, my daughter will often say 'Don't forget, no garlic in mine.' I calmly nod, knowing that she has it an at least half a dozen other dishes (including garlic bread, which she never questions!). Basically this is to do with how it's presented to her, as well as factoring in the texture challenge. As well as the taste of veggies, it is very often the texture that can be off-putting to little palates too, so disguising (or presenting it in a different way) really gets around this minefield.
I don't think smothering vegetables in butter, salt, or more sauce than veg is the answer either, but there are plenty of options.
