Husband has this allergy, too. He can't eat any stone fruit, apples, pears, almonds etc.
We heard that if you eat an apple fresh off the tree you're ok so we went apple picking this fall and he ate his first raw apple in 15 years. No issues, so he ate another and another
I have a food dehydrator so I make him fruit leathers which he likes. He eats a lot of dried fruit, too (dates, figs, apricots)
as for raw, easy to grab foods he likes salads (kale, spinach, lettuce etc are fine for him) cucumber or I make boiled veggies drain them and put them in a vinegar base and he eats them like pickles.
