deconstructed stuffed potatoes

What this really is  - is a mess of mashed potatoes, mushrooms, collard greens, ham, seasoning and some saucy bits to hold it all together. Of course, T took one look at it and pronounced it "gross". D and I ate all of ours and it was good - otherwise I wouldn't share. Or, I would tell you not to make it.

Ham and Collard Green Potatoes (mummydinosaur original)

4 oz (120 g) sliced ham (I measured using my new Oxo kitchen scale - love it!)
1 bunch collard greens, ribs removed, sliced into ribbons
1 c sliced mushrooms
2 1/2 tbsp butter
2 1/2 tbsp flour
350 mL milk
1/2 c grated parmesan cheese
1 tsp dijon mustard
1/8 tsp dry mustard
3 potatoes, peeled, boiled, mashed and seasoned with sour cream and butter

Dry saute the collard greens over medium high heat until just wilted. Set aside. In the same pan, add the butter, mushrooms and ham and saute until the mushrooms are just starting to get brown. Add the flour and milk and whisk until the sauce is smooth. Add the mustards and pepper to taste. Add the cheese and let cook over medium heat for 5 minutes. Add back the chard and stir to break up the chard. Heat for another 5 minutes. If the sauce is a bit thick, add more milk or some stock. Add the mashed potato and mix well and heat for another 5 minutes. Serve. This is a good, stick-to-your ribs supper for a cold and rainy night. If you have those.
