Cricket Coach Seeking Halal Treat Ideas in the UK

Salaam everyone! I'm coaching an under-9s cricket team with many Muslim kids, and with our new local league starting up, I want to be sure the post-match snacks are fully halal. I don’t want any child feeling left out or, worse, accidentally eating something haram. I spotted Bebeto gummies marked halal, but I’d need smaller individual packs like the little Haribo bags-though I know most Haribo aren’t halal. I’m trying to avoid awkward situations by checking ingredients ahead of time! I came across vegan or vegetarian sweets, but I read that sometimes other ingredients can still be haram. So, what should I watch out for, and where might I find good options? Jazakallah khair for any suggestions.
