Mix the wheat flour with salt thoroughly and then prepare the dough by adding water and oil. Add the water in small quantities while kneading and making sure the dough doesn't have any lumps. Too much water will ruin the dough. Keep the dough aside.
Prepare paratha Powder: In a hot pan, saute mustard seeds, cumin seeds, coriander seeds, and fenugreek without oil.
Meanwhile, boil the sweet potatoes and peel the skin and let it cool.
In a processor mash the boiled sweet potatoes and mix paratha powder, salt, and red chili powder.
Roll the dough into small circles and stuff the sweet potato mixture. Fold the edges of the circular dough to cover the stuffing.
Roll the stuffed sweet potato to make a flat roti. It is hard to maintain a circular shape when you are rolling, but it is ok to end up with any shape. Kids enjoy funny shaped parathas.
Place a skillet over medium heat. Grease it lightly when the skillet is hot.
Place the flat sweet potatoes dough (roti) on the hot skillet and flip it when you see raised bumps.
Continue to flip until both sides are cooked.
On the last flip add a little oil on the surface of the paratha and spread it evenly.
