You also could use it to cook some potatoes in and make the best scalloped potatoes ever.
I would use it in bean soup. Ham goes well with any beans.
Use it in rice, either using it place of water or making a gravy.
First of all, my hubby is Franco-Ontarian and gets upset if you call him Quebecois.
Secondly, he is a weird picky eater. He doesn’t eat onions or peppers, or sweets at all, like tarte au sucre. Or poutine. If I hadn’t met his family I would wonder, his French Canadian cred is sure weak.
On the other hand he does love him some tortiere, so that is something.
potato soup
Squirt some into a martini.
Stick with tradition. Boil some cabbage in it.
Nobody’s mentioned red beans and rice yet? Basically, do this, just substitute the ham stock for some of the water. You can omit the sausage or serve it on the side if you want.
Update: After eating ham most of the week, we were all sick of it. I boiled up the bone, with a lot of meat still left on it. As a result I have so much ham stock I made pea soup and something like what bump reccomended. The pea soup is still cooking but the Bumpy Ham soup (which I what I am going to call if forever now) is awesome!
no one said red eye gravy?
I am sad, very sad 
Ham gravy.
