My invented dish I call "Scrumpy". You take fries or fried potatoes, equal amount lettuce broken up like for a salad, chicken, then top it with chicken or beef gravy and chopped green onions. To really take up the indulgence level you can add ~~southern~~ hot sauce like Frank's, and some Cajun seasoning.
It started because of my great love of poutine, and wondering how I could make it into a healthier full meal. I've done a million variations on it, too. Stir fried cabbage and onion instead of lettuce. Corned beef instead of chicken. Adding a fried egg on top... Very flexible weeknight meal.
I would absolutely serve this to someone if it ever came up, but it never has.
