Add warm water, yeast, and sugar in a big bowl. Set aside for a minute. Add the flour and salt and knead for 5 minutes. Halfway through, add little oil and continue to knead. Add little flour for dusting if the dough is very sticky. Once the dough is kneaded, sprinkle a little oil and cover the dough with a lid. Let the dough double in size. It will take about an hour.

Once the dough is doubled, remove the dough to a cutting board and portion the dough into four equal pieces. Set aside.

Add all the ingredients mentioned in the filling into a bowl. Mix well. Set aside.

Take a piece of the portioned dough and spread the dough into a rectangle (about 15cm by 7cm). Apply some vegetable oil on the surface. Spread the filling to cover the middle of the rectangle. Do not stuff a lot of filling. Use it sparingly else folding the dough will be tough. Keep the filling light. Fold one end of the rectangle over the filling and apply oil again on top of the fold. Sprinkle some of the filling again on the fold. Take the other end of the rectangle and place it on top. Spread a layer of oil again on the folded top. Take a cheese slice and cut it in half. Place the cheese slice to cover half of the dough. Fold the remaining half of the dough on top of the cheese slice. Crimp the edges. Set aside. Repeat the same with the remaining dough.

Heat a heavy pan and add little oil. Place the prepared rolls onto the pan. Pour 2 tablespoons of water on the edges of the pan. Cover the pan with a lid and cook on a medium flame for 4 minutes. After 4 minutes, flip the rolls. Sprinkle little oil and pour 2 tablespoons of water from the sides. Cover the pan with a lid and cook on a medium flame for 4 minutes. Our rolls are ready.

These rolls need to be served hot. Enjoy.
