While I have gallbladder problems, what can I safely eat?

Non fatty. Traditional, non fatty, not spicy but you know what has excited symptoms so avoid those and the similar.
Low-Fat Diet. The gallbladder is stimulated to contract most vigorously in response to high-fat foods, therefore it is best to avoid these. Nevertheless, a better answer may be "nothing": any food can precipitate a gallbladder attack once you have stones.
