Bean casserole made easy

This is my mother's recipe. It looks a rather muddy mess, but is actually very tasty!

Serves 2 good helpings

400 gm tin of butter-beans
400 gm tin of tomatoes
8 or more dried apricots
1 onion, grated or chopped
2 bay-leaves
1 full teaspoon of Marmite
Salt and pepper

Mix all the ingredients together the night before, cover and leave to stand, so that the apricots can absorb the flavour. Add more liquid the next day if necessary. Cook in the oven for one hour at 180 degrees.
