Cheese and onion pie is a British institution just like fish and chips! You can definitely tell this as this recipe is my most viewed - by over 100,000 people! I tried a few recipes to make this and realised that with the addition of water it makes the pie more moist, so you can have it without a sauce. The milk brushed over makes it brown evenly too. My daughter has this with mashed potatoes and beans, but you can have it with a side salad, with chips and beans, or new potatoes and other vegetables like carrots, cabbage or green beans perhaps. I prefer the ready made pastry here but I have sometimes made my own and it has been just as good. This doesn't really work with any other cheese but mature, and extra mature cheddar. You could try it with filo pastry too for a lighter pie if you like. Fussy guests never refuse this, and even ask for more....
Here is the recipe
