Step 1: Prepare the Crust
Brush the bread with vegetable oil (or rendered bacon fat if you have it), press another identical dish on top, then place it on a metal tray in the oven (180C) for 20 minutes, or until the bread is pale golden and crispy.
Step 2: Prepare the Fillings
A rasher of bacon, rolled up. Put these in another ovenproof dish and bake alongside the crust until crispy and cooked through
A sausage, a couple of mushrooms and some thin slices of potato. Fry these gently in a little oil until cooked, but not too browned.
Black Pudding (I used a Spanish Morcilla) - a couple of slices - these need only a quick sizzle on each side in the pan, after the sausage is cooked.
Step 3: Assemble the Pie
Arrange the fillings inside the crust - you'll probably need to cut the sausage in half.
Crack a couple of whole eggs into the middle of the pie, over the top of the other fillings.
Add a couple of baby plum tomatoes.
Bake in the oven (160C) until the eggs are done (15 to 20 minutes)
Remove from the oven and top with a spoonful of warmed baked beans.
