Here is the recipe for Lord Woolton pie, the staple of WW2 rationing and just the thing for Dad's Army!
Take 1Ib each of diced potatoes, cauliflower, swedes and carrots;
Three or Four spring onions;
One teaspoonful of vegetable extract and
One teaspoonful of oatmeal.
Cook all together for ten minutes with just enough water to cover. Stir occasionally to prevent the mixture from sticking.
Allow to cool; put into a pie dish, sprinkle with chopped parsley and cover with a crust of potatoes or wholemeal pastry.
Bake in a moderate oven until the pastry is nicely brown and serve hot with brown gravy.
