I haven't made this recipe, but a note to A Cook, I don't know what soup recipe you are talking about, but for years (even before it was ever printed on Cambell's soup label) I have added Cheddar Cheese soup mixed with about 1/2 can of milk to my scalloped potatoes and ham. I just layer my potatoes, then onions, ham, and soup mixture, plus any spices I may add (salt, pepper, galic powder, maybe a little basil) and bake until potatoes are tender. Oh, and I use food processor to slice potatoes and onions. Hope this helps. My own opinion on the velveeta, I love velveeta, so I think this recipe would be good.
