Add the flour, coconut, salt, onions, and green chilies to a bowl.
Sprinkle water as needed and knead to a dough. Cover and rest for five minutes.
Divide the dough into nine portions. On a flat oiled surface/aluminum foil, gently roll each portion of the dough into a disc of 7 to 8-in diameter.
Heat a pan on medium heat, when it is hot, transfer the flattened roti on to the tawa by flipping the foil paper and gently pushing it onto the pan. Cook for 2-3 minutes. Flip and cook the other side. A little oil can be used while cooking the roti.
Transfer to a platter. Repeat with the remaining dough portions. Serve with Lunumiris or pol sambol.
