My father used to make a casserole that had a wonderful flavor, but, alas, I never got his recipe. I asked his sister, but she couldn't really remember how to make it either. He was Romanian in case it was a regional dish, but here is what I remember: sliced potatoes (my aunt said to precook the potatoe slices on the stove top, don't know if my dad did that or not), cooked ground beef, and some type of tomato base, either Campbell's tomato soup, tomatoe juice or something I am completely unaware of--there were no chunks of tomato in the dish.
His casserole had a flavor that was more than the sum of its parts. If anyone has any ideas, please let me know!
