2. Mix the chopped vegetables with the grated cheddar cheese.

3. Assemble the Rolls

1. Preheat your oven to 180°C (350°F).
2. Punch down the dough and divide it into small equal portions.
3. Roll each portion into a ball, then flatten into a small circle.
4. Place a spoonful of filling in the center of each circle.
5. Fold the edges over the filling and pinch to seal.
6. Arrange the rolls on a parchment-lined baking sheet, cover, and let them rise for 15-20 minutes.

4. Bake the Rolls

1. In a small bowl, whisk together the egg yolk and olive oil.
2. Brush the mixture over the rolls for a golden crust.
3. Bake for 20-25 minutes, or until golden brown.

5. Serve & Enjoy!
