What to do with a Pork Hock

[Sundae]

From searching on the internet it seems the American term "pork hock" differs from the British cut. So I have included a photo. These pre-packaged pig parts are approx 3.1oz.

Now I am only just getting to know this supermarket
But I already know that as well as having talented and very attractive staff, they don't sell many of these and until the ordering settles down into automatic stock control, these will be discounted heavily.

So I was wondering what I could do with them?
They are already roasted.
There cannot be much meat on there.
Are they really only good for making stock?
Every recipe I can find online is about how to cook them...
