Mix the wheat flour, salt, water, and oil. Mix the dry ingredients first followed by oil. Add water in small quantities and knead the dough until there are no more lumps. (if required grease the hand with a little oil then knead the dough)
Prepare small balls from the dough and place them aside.
Take one roti dough ball and start to roll the dough into flat circles with a rolling pin. Repeat this procedure for all the dough balls.
Place a skillet over medium heat.
Place the flat dough (roti) on the skillet. When you see the little bumps. Flip the roti on the pan and let the other side of the roti cook on medium heat for 30 seconds or until there are very light brown spots on the side that are facing the pan.
Once both sides are half-cooked as noted above, take the pan off the stove and place the roti directly on the flame (medium/high). The side that was cooked initially should be facing the flame. It should fluff up like a big ball.
Take it off the flame and place it on a paper towel or a hot box. Spread a little amount of oil or vegan butter, if you so prefer.
