I wanted to come up with an easy, cheap but satisfying meal for one, I actually cooked it for 2 but the recipe below is for one, add one extra of everything per person to cook for more.
Slice onions and cut potatoes into match stick size lengths
Pour half the oil into a frying pan
Add onions and potato and cook till the onion starts to brown
Add a glass of milk and simmer for 5 minutes.
Put some more oil into an oven proof dish and put the sardines onto the oil.
After the potatoes and onion have cooked in the milk pour over the sardines
bake in the oven at 200°c till browned.
This works so well served with a decent beer.
