Some of the measures are a little difficult to translate, I've had three different answers, from Portuguese friends, but here goes.
500g chicken or turkey breasts, battered and sliced thinly
2 jars of sliced mushrooms - you may not be able to get this in England, but very popular here, as fresh mushrooms are very expensive (basically use as many or a least as you want)
1 spoon of pimento doce, so use paprika and as much or as little as you want - I used a dessert spoon
i onion. sliced in half moons ( love the description )
40g butter
200ml olive oil
600mil cream - this is where you may fall down - the cooking cream we get here is very very different to what you get over there, it's quite thin.
2 dessertspoons of mustard
white wine or white port - about 200 ml - I put in ruby, as that was all we had and about 300ml
parsley to garnish
Melt half the butter in a thick bottomed pan and slowly warm up the mushroom. Do the same with another pan with the onions, very slowly.
Season chicken/turkey with salt and pepper.
Put chicken in another pan with the oil (I used the same one, just took stuff out) add the chicken and cook until white, add onions and stir. Then add pimento, mustard mushrooms and stir again. Add cream and port or wine and cook, simmering for about 10 minutes.
Serve over tagliateklli or rice - as this is Portugal. maybe thin chips . Sprinkle over the parsley.
Enjoy. We did Even though it was a little pink, due to the ruby port
