The pork and kraut thing always works. A soup would be good. Add some mole sauce and make tamales or enchiladas. Now you've got me thinking about what I might do with some leftover pork roast I've got. Hmmmmmm!
Make a sandwich...sliced cold pork roast, whole wheat bread, romaine lettuce. You can save some for when you make a tomato sauce.,,can wrap and freeze. Chop some over brown rice and some veggies. Make a hot pork with gravy sandwich..add ..veggie or salad.
