My mom used to dice the ham (in good-sized pieces) and put it in a cheese sauce. Chunk up a couple of hard-boiled eggs and add that to the sauce, too. Then serve over home-fried potatoes.
Chunked up ham in baked beans, served with/over corn bread. OR make fancy corn bread using a mix (we like jiffy) and add chunked up ham, diced sauteed red and green peppers, diced sauteed onions, spread it in a baking pan and sprinkle with cheese. Sorry I can't give you specific measurements; my mom was more of a "cook by sight" than by measurement cook!
There's also split pea soup, multiple bean soup, ham/white bean/mixed greens soup. Fold it into scalloped or au gratin potatoes (I do this with the box-mix potatoes).
A favorite (although eclectic) recipe from my childhood was to slowly warm ham in a milk/brown sugar sauce and serve with mashed potatoes. My mom never thickened the milk, but I guess you could do this with a thin white sauce. Yes, I realize it's probably an "acquired taste" but we really like it!
