Instructions
1 Preheat oven to 225°C and line a large oven tray with baking paper.
2 In a large bowl, place yeast, sugar and water and leave for 5 minutes or until frothy. Add flours and salt and mix using your hands until a sticky dough forms. On a floured surface, knead until dough is smooth. In a lightly oiled bowl, place dough, cover and leave in a warm place to rise for 30 minutes.
3 Heat oil in a large frying pan over medium. Add onion, garlic, carrot and capsicum and cook for 2 minutes before adding remaining vegetables. Cook until tender. Add tomato passata, chopped tomatoes, herbs and pepper. Cook for 5–10 minutes to reduce slightly. Remove from heat and leave to cool.
4 On a floured surface, place dough and punch down to deflate. Divide dough into two equal pieces and dust with flour, then roll out to two large rectangles (about 25cm x 30cm).
5 Using a ladle, spoon filling over dough, then sprinkle one cup of cheese over the top. Roll up the long edge of each piece of dough into pinwheel. Using a sharp knife, cut each log into 10 equal pieces and lay on their sides on oven tray. Sprinkle with extra cheese and place in oven. Cook for 12–15 minutes until cheese is golden and bubbling.
