Take a few mushrooms, a couple of rashers of bacon and a slack handful of fresh parsley:
Heat a small quantity of cooking oil (I used Rapeseed) in a frying pan. While the oil is heating, slice the mushrooms, dice the bacon and chop the parsley.
Add the bacon to the pan and fry for a couple of minutes until it begins to brown slightly. Add the mushrooms and cook for a further two minutes.
Toast a piece of granary bread.
When the toast is ready, add the chopped parsley to the pan with the bacon and mushrooms and mix it in.
In the time it takes you to butter the toast, the parsley will have wilted. It is now time to serve the dish.
Put the toast on your plate and pile the bacon etc onto it, like so:-
There you are, it's ready to go. Probably quicker, and certainly nicer, than popping down to Greggs' for a pasty!
I didn't photograph this aspect of the proceedings, but I added a generous dollop of tomato ketchup to the dish before eating it...
