Bread: liberally spray the bowl, blade and lid of a food processor with cooking oil. Then add the plain flour, yeast, sugar, salt, milk and butter. Blitz for 30 seconds to combine then tip out onto a lightly floured surface and knead for 20 seconds. Place into a greased mixing bowl, flip to other side then cover with cling wrap and a tea towel. Leave for 1 hour to rise (1st rise).
Bacon cheese layer: add the butter, tomato paste, dried onion, dried basil and dried oregano to a medium size mixing bowl and stir to consistently combine. Next add the diced bacon pieces and stir to gently fold in.
Roll: once the 1st rise time is up remove the tea towel and cling wrap. Lightly sprinkle the bench with flour then tip the dough out onto the flour. Use a rolling pin to roll the dough into a large rectangle the size of a big pizza. Ensure it is 'thick crust' not 'thin'.
Layer: next use a soup spoon to dollop the bacon mixture onto to the rolled pastry. Then use the back of the spoon and spread this out across the dough leaving a slight border at the edges. Sprinkle the mozzarella cheese over the top of the bacon layer.
Loaf tin: grease a 21 x 11 x 7 cm non stick loaf pan (8.3 x 4.5 x 2.75") with cooking spray.
Slice and stack: use a pizza wheel to cut the rolled dough into pieces (approx 16 in total) then stack a row of the slices in your hand and place these into the prepared loaf tin in a vertical direction. Repeat to fill the loaf tin with the pieces, pushing them to the front of the tin to fit as needed. Cover the loaf tin with cling wrap and a tea towel. Leave to rise for 25 minutes (2nd rise).
Loaf tin: grease a 21 x 11 x 7 cm non stick loaf pan (8.3 x 4.5 x 2.75") with cooking spray.
Preheat oven: to 180°C / 350-375°F / Gas Mark 4-5.
Tent: make a aluminum and baking paper tent to cover the bread sticking the 2 layers together with a spray of cooking oil.
Oven bake: remove the tea towel and cling wrap then cover the bread with the tent. Pour 1-2 cups of water into a baking tray on a lower rack under the bread. Place the tent covered loaf tin into the preheated oven on the middle shelf. Bake for 50-55 minutes and test with a skewer that should come out clean to ensure it is cooked through.
To serve: use oven mitts to remove the cooked bread from the oven and set on a heatproof surface. Remove the tent. Let sit in the tin to cool (5-10 minutes) before using a butter knife around the 4 edges of the tin to gently break the seal and slide out. Plate and serve warm and fresh!
