I love traditional bread-and-butter pudding with raisins and nutmeg, all hot and gooey and served with custard. This is a savoury variation that makes a delicious and cheap vegetarian main course.
Cheesey Bread Pudding
Butter 8 slices of bread and make sandwiches with grated mature cheese and sliced onion. Quarter the sandwiches and arrange in a baking dish. Feel free to vary to contents of the sandwiches. If it doesn't have to be a vegetarian dish, some ham would be very nice. Or you might want to put some pickle on the sandwiches, some sliced tomatoes, cooked sausage or whatever you fancy.
Beat 2 eggs with some milk, salt and pepper, and any other flavourings you like. I just rummage through the cupboards and see what I fancy - sometimes it's a generous helping of mixed dried herbs, or I might grab some fresh herbs from the garden. Or I might go for mustard powder, tabasco, or horseradish if I feel like something a bit spicy. It's up to you. It's that sort of recipe. You need plenty of liquid though, so add more milk until you think you have enough mixture to soak the sandwiches thoroughly. I reckon about half a pint or so.
Pour the flavoured eggy mixture over the sandwiches. If you had any cheese leftover, sprinkle it on top. Onion, too if you have any. Now bung it in a moderate oven for 25 minutes or so, until the eggy mixture has set and the cheese on the top is golden.
In a nutshell - it's cheese sandwiches with savoury custard poured over then baked in the oven. Now you know how to do it, go and invent your own family's favourite version.
