Brown the lardons in a frying pan over a high heat. Add the sliced mushrooms and chopped broccoli – cook for 5-7 minutes, stirring now and again, until the mushrooms have reduced in size a little.
Add the wine – let it bubble down a little, then add the creme fraiche, gnocchi and 100ml water. Bring to a simmer and cook until the gnocchi is squidgy to the touch.
Season with salt and pepper, pour into an oven proof dish and evenly crumble over the Cheshire cheese. Cook under the grill until the cheese is melted and starting to bubble. Enjoy!
