Help Food ideas- 2 year old with dairy, egg, nut and sunflower seed allergy

Hello, I’m in desperate need of meal ideas for my son. He was diagnosed with dairy and egg allergies at 6 months old and since then I’ve struggled to feed him. He’s also in feeding therapy because he will not eat anything other than rice and apple sauce. He recently had an allergic reaction from a vegan Mac and cheese and today I found out he also has a nut and sunflower seed allergy. I’m been struggling so much to feed him and don’t know much of what to offer him that has no eggs, dairy nuts etc. I would really appreciate suggestions.
