I make a savoury *bread based quiche* from slices of bread....
Grease a large, flattish baking dish and place thick slices of the bread over the base (cut triangles etc to fill in the gaps). Fill the centre of the dish with cubes of the bread, especially good if you make sure the crusts are at the top of the *pile*.
Grate about 6-8 ounces of strong/mature cheddar. Beat up 2 large eggs (I use free range) eggs and about a quarter pint of milk and mix in the grated cheese. Pour this over the bread, allow to soak into the bread for at least 10 minutes, sprinkle some cayenne pepper (if liked) over the top. Don't worry if some cubes of bread are not in the egg/cheese mix, so long as they've had some egg/cheese added, they will puff up and form a lovely crusty top. Bake in a pre-heated oven, Gas 6, 200 deg C for about half an hour until golden brown.
It's basically a savoury bread & butter pudding with the cheese replacing the butter and fruit.
