Easy savoury tart

Bring milk, bread and margarine to the boil. Boil for 3 minutes. Allow to cool.
Place Russian sausages into boiling water to draw out sharp flavour. Remove from water and pat dry. Slice thinly. Add to bread mixture.
Quarter and slice onions. (Do not chop finely or too much onion bulk will be lost when frying.) Fry onion lightly in oil. Add to bread mixture.
Chop eggs and add to bread mixture. Add flavouring and half of the cheese. Stir in the beaten eggs. Mix lightly but well.
Spoon mixture into greased aluminium foil containers of your choice. Sprinkle with parsley and remaining cheese and bake at 180 ºC.
