Okay, so I did find a "pie, mash, and liquor" recipe on the net. A meat pie (one site had mutton, the other beef), mashed potatoes, and a parsley bechamel sauce. Sound right? The recipe I found was at
Uncle Phaedrus, Finder of Lost Recipes
Don't know if I can try it right away myself (my kids and husband are picky eaters, especially when it comes to anything green) so if anyone else decides to try it I would love to hear how it is.
