Chicken (Or Mushroom Or Tofu) Tortellini Filling - cooking recipe

Ingredients

3/4 ounce butter
2 3/4 ounces chicken breast fillets, cubed (I've used tofu before, and also mushrooms--with a little extra salt for flavor for both)
2 slices pancetta, chopped (never added this, don't eat pork)
1/2 cup grated parmesan cheese
1/2 teaspoon nutmeg
1 egg, lightly beaten (I've used 2 egg whites before)
salt and pepper (to taste)

Preparation

Heat butter in a frying pan, add chicken (or tofu or mushrooms or whatever) until golden brown, then drain.
Process this in food processor (along with the pancetta, if you choose to include it) until finely chopped.
Transfer to bowl and add cheese, nutmeg, egg and salt and pepper to taste.
Fill pasta and seal edges with egg whites (use a pastry brush to apply this, or your impeccably clean hands).
