Essentially you are in the right ball park.
Seasoning, maybe some crushed garlic too. I'd mix a harder cheese in such as Parmesan as just cheddar could be a bit greasy. Is blue cheese too scary for the family?
When I've done them I've removed the stalks and chopped them up finely with a little garlic and onion ans fried before adding the breadcrumbs, seasoning and when cooled add cheese before filling. Then when filled dip them into a bowl of Parmesan and breadcrumb mix.
