Get some salmon fillets, skin them, then flash them up quickly in a pan until they change colour. Add salt and pepper to taste as you do this.
Then pour over some runny double cream and add the herb of your choice as you wait for the potatoes to boil.
Cook whatever vegetables you like.
Heat up the salmon and cream to finish off the cooking, then mash the spuds and serve it all out, making sure you pour the cream and salmon over the spuds. That's it.
Your guests will not believe that you have not slaved over this dish for at least an hour, nor will they believe that the only other ingredients are merely salt, pepper and herbs.
Try it - it works - that's what I am cooking tonight.
