What are some good foods for someone with a restricted diet due to pku?

Vegetables are OK. Phenylketonuria is treated with a low phenylalanine diet, which means most proteins are verbotten. But people with pku need expert guidance from a metabolic dietician and biochemical geneticist to do it right. Too much protein restriction can be just as bad. You need to have your phenylalanine blood levels checked regularly. If you are a woman of childbearing age, you have to be even more careful.
