I've been cooking alot for a couple of family members who tend to not like vegetables. Cruciferous ones (cabbage, broccoli, cauliflower, kale, etc) are a particular problem, although they also say they don't like leeks. They say all of the above don't agree with them, and won't go into detail.
I'm wondering if it's the amount of fiber in these veggies that bother them, or some sort of chemical compound that induces gas. Does anyone know if doing, say, a broccoli puree instead of a solid preparation would help with these complaints?
