Have made this several times and it's a great way to finish off the leftovers. I usually save a small amount of leg/thigh meat that would normally go to turkey salad.
Dice turkey in small pieces.
Dice precooked potato in small pieces. I use an equal amount of potato to turkey.
Dice a lesser amount of onion, I like about half of potato/turkey amount.
Sauté onion and potato in olive oil. Add turkey and reduce heat. Let simmer till turkey is warmed thru. Drop an egg or two on top, cover and cook on low till egg is cooked.
