Looking for a recipe for leeks cooked in strong British mustard

[Discerning1]

I was served a delicious hot side dish on, of all things, a Virgin Atlantic flight from the UK to SF. It had chopped leeks and was cooked in a strong British mustard.

I've searched the internet and can't find a recipe. Anyone have an idea of how it was prepared?

Leeks seem to be a popular British veg.

Leeks are, indeed, very popular here as they grow well here - and, as already pointed out, a good way to serve them is in a mustard & cheese sauce (or simply mustard flavoured bechamel).

Here's a simple main course version that I like:

There was a piece in the times a few years ago about braised leeks with a strong Dijon vinaigrette. I can't find the exact article and I know that the below link is not exactly it but it seems close. Try it and swap English mustard for the Dijon.

Did there seem to be cheese in the sauce? Here is a BBC Food recipe for:
