This is a variation on a pie that my brother's girlfriend made for us over Christmas. The ingredients in brackets are my variation. You can make it either way and feel free to add your own extra's.
Roast chicken, stripped (2 cooked chicken breasts cubed)
1 chopped onion
4 rashers of bacon, raw (10 rashers of streaky/American bacon, raw)
2-3 cans of Campbell's cream of mushroom soup (3 cans of Campbell's cream of mushroom soup)
(I added: a good shake of paprika and a few handfuls of baby carrots cut into thirds.)
Put chicken, onion, bacon (chopped and raw), soup and anything else you fancy into a bowl and mix.
Put mixture into a 9x13 pyrex dish.
Cover with pastry. I use one package of Pepperidge Farm puff pastry. Fold under the extra dough around the edges to lift it off of the soupy mixture a little.
Score the top of the pastry but don't cut all the way through it - this helps it puff up better.
Bake at 375'f for 45 minutes.
Garlic Parmesan Mashed potatoes
Potatoes with skins still on - I make enough for leftovers to go with the leftover pie.
Salt and Pepper
Boil the potatoes until soft and strain
Put potatoes, a good nob of butter, good shake of garlic powder and a splash of milk in a big bowl.
Use a handheld whisk or food mixer to whisk the potatoes.
Once chunks are all out add more milk, salt and pepper, mix again.
Taste. Add more of what you think it needs. You can also add some cream cheese to it.
Once it's the consistency you like - I like them light and fluffy so I whisk them on high for a bit and add a touch more milk to fluff them up.
Once it tastes good put it in an over safe dish, don't squish it down.
Put a few pats of butter on top and sprinkle parmesan cheese over.
Put in the oven with the pie for the last 20 minutes or so of baking.
