You will need:
Thinly sliced raw turkey breast (I usually put it on a board, cover with clingfilm and bash with rolling pin if they look a bit on the thick side)
Half a lemon, or bottled lemon juice
Seasoned flour
4 tablespoons chicken stock
4 tablespoons freshly grated parmesan
4 tablespoons of Marsala wine
50-75 gramms of butter.
Rub the turkey steaks with the lemon (or slap the juice on with a pastry brush) and coat in the seasoned flour. Melt the butter in a large frying pan and cook the meat over a gently heat for about 10 minutes, turning until golden brown on both sides.
Add the marsala and allow to bubble for a bit. Sprinkle each fillet thickly with the parmesan, and moisten with the chicken stock. 9I have been known to forget this stage, and then wonder why there is a jug of stock on the worktop. This usually happens because I have either been nattering away as I cook, or I have had the extra glass of wine that makes you lose concentration 
Cover the pan and gently simmer for about another 10 minutes until the fillets are tender and the cheese has melted.
I tend to make extra sauce by adding extra marsala, if you do thid it is a good idea to add the rest of the flour and cook it a bit before adding an increased of wine.
It's very yummy, is quick to make and doesn't make much washing up!
