# Ingredients Required:

→ Dough

01 - 240 ml sourdough discard (unfed, room temperature)
02 - 60 ml warm water
03 - 1 tsp instant yeast
04 - 1 tsp granulated sugar
05 - 210 g all-purpose flour
06 - 1/2 tsp salt
07 - 30 ml olive oil

→ Filling

08 - 115 g sliced salami
09 - 115 g sliced pepperoni
10 - 115 g sliced ham
11 - 100 g shredded mozzarella cheese
12 - 25 g grated Parmesan cheese
13 - 1 tsp Italian seasoning

→ Finishing

14 - 1 egg (beaten, for egg wash)
15 - Marinara sauce (optional, for serving)

# Guide to Cooking:

01 - Combine sourdough discard, warm water, yeast, sugar, flour, salt, and olive oil in a large bowl. Knead until a soft dough forms, approximately 8 to 10 minutes.
02 - Cover the dough and let it rise in a warm environment until doubled in size, approximately 1 to 2 hours.
03 - Set the oven temperature to 190°C and line a baking sheet with parchment paper.
04 - On a lightly floured surface, roll the dough into a rectangle about 6 mm thick.
05 - Evenly layer salami, pepperoni, and ham over the dough, leaving a small border. Sprinkle mozzarella, Parmesan, and Italian seasoning on top.
06 - Carefully roll the dough lengthwise into a log, tucking the sides in to contain the filling. Place the log seam side down on the prepared baking sheet.
07 - Brush the top with beaten egg to promote browning. Optionally, cut small slits on top to release steam during baking.
08 - Bake in the preheated oven for 30 to 35 minutes until the crust is golden brown and crisp.
09 - Allow to cool briefly before slicing. Serve warm, optionally accompanied by marinara sauce.

# Extra Suggestions:

01 - Ensure the dough has doubled in size before shaping to achieve a light and airy texture.
