Mushrooms on toast

I was once contemplating making this for a late evening meal when Granny rang. I told her, rather smugly, of my plan for supper and she was most impressed. Whether I then made it that evening I am not sure.

It is based on a Nigel Slater idea in "Fast Food" - although I suspect he would be the first to deny that it is a recipe.

INGREDIENTS:

Sliced mushrooms

Finely chopped onion

Olive oil - for frying

Double cream

Some fresh parsley

Possibly a scrap of bacon

Toast

METHOD:

Heat the oil and gently fry the onions. Add the mushrooms; I think they should be slightly crisp. Add the bacon if you're adding it. Then the cream and let it all bubble and reduce. Pour on to the toast and eat immediately.
