Add the salt and pepper to the mixture, to taste. To a third pan, add the olive oil and onions. After the onions turn translucent, sauté the spinach with it, till its moisture evaporates, completely. Add ½ a cup of the sauce and nutmeg to the mixture, and heat it, again. On a platter, spread the spinach out and place the sliced turkey pieces on top of it. This recipe can be served in a casserole.
