My wife can't eat onion, beans or garlic. What are some of your favorite recipes without them?

Do you know if this is some specific allergy or a general food sensitivity? I am sensitive to fructans, which are a FODMAP in all of those foods, except the green parts of an alium (garlic, scallion, onion, leek). I take an enyzme called Fodzyme which helps me digest fructan rich foods when I can't avoid it.
