Dry roast all the flours separately and allow it to cool down.
Mix all the flours in a wide bowl, add in all the spices and onions. Slowly add warm water and knead to a stiff dough. Divide the dough into equal balls.
This roti needs to be patted down, so on a wet cloth or plastic sheet, pat down each ball into a circle.
Heat a tawa, grease with cooking oil. Gently transfer the rotis and cook on both sides.
Serve it as well as the spice is enough, else this makes a great combination with chutneys.
