Quite surprised you haven't tackled "Poor Man's Potatoes" yet. Lots of recipes about - here's the first one that came up:
http://www.orceserranohams.com/poor-mans-potatoes/
...and as a bonus, I shall throw what is -as far as I know- an original recipe. I call it "Cheese'n''Ting". A variation on cheese on toast. No recipe; but here's the layers:
====== <---- Cayenne pepper to taste
====== <---- Cheese - decent cheddar for preference
====== <---- Chopped button mushrooms (thin layer to cover the bread)
====== <---- Hoi Sin Sauce
====== <---- Lightly toasted bread
...you wouldn't think it works, but somehow it does; it depends greatly on the Hoi Sin sauce...you want the more meaty-flavoured sort and not the incredibly sweet sort. I was quite thoroughly "back from the pub" when it was invented; but it has since passed the "is also delicious when sober" test.
