Mix the flour, baking powder, sugar, 1/2 teaspoon salt and water into a dough. Coat the dough with oil and leave to rest for 45 minutes to 1 hour.
Cut the potatoes in half and boil in 1 teaspoon of salt. Peel and crush the potatoes with the back of a fork and add geera, green seasoning, garlic and 1 teaspoon salt. Mix thoroughly and set aside.
Divide the dough into 8 loyas or balls. Open out a ball and sprinkle a bit of flour. Then add about 2 tbsp of potato.
Pull the edges together at the centre to form a ball again. leave to rest for 5 minutes. Roll out the ball on a floured surface and place on a hot oiled tawa.
Note: Keep a little saucer or bowl of oil close so you can oil the tawa occasionally and spread a little while cooking the roti on both sides.
Fold over once and place in bowl lined with paper towels or a piece of cloth.
