- In a bowl, combine flour, salt and oil and mix well. 
- Add enough water to make a soft dough. 
- Cover and set aside for three or four hours. You can also leave it in fridge overnight. 
- Divide the dough into four equal portions. 
- Apply butter on the dough as well as the counter. 
- Roll it into a thin rectangular flat bread. 
- The bread should be transparent enough so that the counter can be seen through it, but be gentle as we don't want any holes on it. 
- Place sliced banana inside the centre. 
- Fold all the four sides of the bread to make a square pocket. 
- Now heat a tawa. 
- Drizzle ghee on the tawa and gently transfer the prepared pocket to it. Cook on both sides until brown and crisp. 
- Remove it on to a cutting board, slice it into 9 equal squares. 
- Drizzle condensed milk and chocolate sauce over it. 
- Sprinkle sugar and serve immediately.
