This is great, I was going to type up a recipe and then I found this video when I was looking for the tofu one. If you don't feel like making your own chapatis use whole wheat tortillas.
My recipe makes more chapatis and uses half whole wheat and half regular flour otherwise it's the same.
This recipe makes 4 Roti's:
1/2 Cup Whole wheat flour
Pinch of Salt
1/4 Cup and 1 tablespoon of luke warm water
1/4 teaspoon of Oil
1 teaspoon of Ghee or clear butter
