You will need: Mince and onion pie(s) (as required) Tin of mushy peas (not Morrisson's) Potato product (optional)
Method: Heat oven to 180c. Place pie (I used a Dickson's) in oven for 15-20 minutes. Heat peas (I used Asda's as Morrisson's add mint which is vile) in microwave for up to 2 minutes.
Serve.
You can include chips or mash if you like. I used some new potatoes (heat in boiling water for 15-20 mins, drain, serve) which rendered mine un-local but bulked it out a bit.
Proper Northerners add gravy too which I think is unnecessary.
