Chicken breasts with Oporto’s wine sauce

Chicken breasts with Oporto's wine sauce for 4 people:
-4 Chicken breasts
-1 spring onion
-200 gr mushrooms
-400 cc cream
-200 cc Oporto's wine
-olive oil
-salt, pepper

Pour the olive oil on the frying pan and add the chopped spring onion and the sliced mushrooms, add a teaspoon of salt, stir, and remove when it'll be cooked. Pour another squeeze of olive oil on the frying pan to fry the chicken breasts, previously salted, until browned, then add the mushrooms and onion, previously cooked, pour the cream and the Oporto's wine, blend well, cover, and cook over low heat for 20 minutes. When it will be almost finished sprinkle a dash of pepper. It's ready to serve!

Advice: If you don't like mushrooms and/or spring onion, you can rule them out, or replace the spring onion for a leek, or an onion. Also you can use other kind of red wine (it won't be the same..... but it is a good option)
