Hello, I am also having a bad IBS time at the moment and am on low FODMAP, though not as restricted as yours!
I had a sort of potato salad thing today with potatoes, ham, cucumber, carrots all mixed together and covered in olive oil. I added in a splodge of mayonnaise but if you have other intolerances this might be a problem for you. If you can manage a few drops of lemon juice that would add a bit of zing, but I am guessing from the above you are off all fruit. This is good one to take out as well as it's nice cold.
We have potato wedges made by coating the potato in oil and paprika and cooking in the oven a lot. They are nice with mince. I can't seem to tolerate shop brought chips for some reason so this is my chip fix.
Otherwise, lots of roast dinners with the list above.
How about fish? easy and versatile and something a bit lighter then meat and potatoes?
I did actually burst into tears in a cafe the other day. Me and DH had a rare chance for a child-free lunch out and after spending ages finding something on the menu I could eat it turned up and they had fried some of the veg in garlic. Everyone around me was eating delicious sandwiches and cakes and it all just got a bit much
Poor DH was very sweet and took me to m&s to buy ham and carrot sticks.
Today we had a hot potato salad with pancetta which was lovely. I think it's going to be beef stew for dinner with lots of random herbs to try and flavour it.
