Is there a way to create a user who can only change the prize value in the backend?
Not really. There is of course the option to restrict a user to be able to edit menu items only (WPPizza->Access Rights) but if you want to make this even more restrictive (i.e perhaps restricting to being able to use the quick edit only for example) you might want to try something like this https://www.role-editor.com/forums/topic/restrict-access-by-role-to-quick-edit-functionality-on-post-listing-screens/ or similar
