@Sturgis,
Ah most have eaten left overs in the morn when starving, was it after the red wine?
Potatoes in an omlette there you go, all sliced up thinly, add what ever else you want, but yeah I've done that before.
Actually SPADES ahhhh, I've had mash potatoe on toast in the morning as left over mash , but butter "had" to be there too and the potatoes had to be microwaved...
Don't mind that idea either.
for no "fat".
Not that I've ever looked at them
