Slice chicken breast into cutlets or you can use already sliced store bought cutlets. Season with salt and pepper.
Dip each cutlet in flour and dredge both sides.
In a large skillet pan placed over medium heat add butter and a generous splash of extra virgin olive oil.
Brown chicken cutlets on each side. Remove from the pan and set aside.
In the same pan add white wine, stir well and simmer for a minute.Add tomato puree (if it looks too thick add some water), basil leaves and simmer on low heat for 5-7 minutes.
Place chicken cutlets you’ve previous set aside in tomato sauce, top with mozzarella slices, season oregano. Cover with a lid and simmer for another 5 minutes until cheese melts.
