Seared Salmon with Parsley Sauce

If you have never had parsley sauce you are not alone. A traditional English sauce, it seems to have not quite made the journey over to us in the States which is a real shame because it a truly delicious condiment. I first had it when my British mother-in-law served it while we were visiting them in England some years back and this recipe is my own take on the traditional recipe.

You can serve this dish with any vegetable you like but I am particularly fond of serving it with simply steamed baby potatoes tossed with a few knobs of butter, a couple tablespoons of fresh chopped parsley and a pinch of salt and then mixing in some petit pois (aka: green peas). It’s one of those filling, wholesome and healthy dinners that make you (or my British husband) think of home.
