Assembled this last night - Lidia’s meatloaf was a bit dry (partly my fault, forgot to serve it with tomato sauce). So it’s meatloaf casserole. Leftover meatloaf, a bit of leftover sauce on top:

Onions, of course, because they make everything except dessert better:

Then a layer of sour cream mashed potatoes, and top with grated cheddar. In the oven now - smells great.
