Are Autistic parents buying any snacks that aren’t cheese-its and Goldfish?

I've had my son in something called the picky eaters group and even in food therapy. He will try certain things but he's never adapted to it outside of therapy. Needless to say I stockpile goldfish and cheese-it's. Has anyone had any luck with other snacks? Fill me in please if you've had luck with anything outside carbs.
