Same problem here, no gall bladder. For me it’s fried foods and greasy things (including stews with fatty gravy). At Disney, I am super careful, because who wants issues there? Most places have grilled chicken, which is safe for me. At Rose and Crown, I didn’t think I would tolerate most items on the adult menu, so I requested and got an adult portion of the kids grilled chicken dinner. Grilled fish or even lean steak work. I usually get a side salad instead of fries. I can eat some fries, though. I think she can ask if she doesn’t see anything. A key learning for me it to ask how things are prepared.
