Here are some of my dinners from the last two nights to show that lower fibre doesn't mean no veggies at all- I just make sure I have white rice or pasta with them. The first is vegetables in rice with a little creamed coconut cream grated in and some thai spice mix, parsley and lime juice. I topped it off with a nut cutlet.
The second is the scraping off the tin of my leftover tofu, kabocha and chestnut pie with some pasta and rocket.
At the moment I pretty much eat no fruit and veg until my evening meal. I am hoping to gradually add some more back, but when I first did the low fibre thing I wasn't even eating whole vegetables for dinner.
If you haven't tried cutting down on whole grains and vegetables to help your IBS, I would definitely recommend giving it a go. It has worked wonders for me, although I do miss eating lots of salads and brown rice:(
