Make a dough with the ingredients mentioned under outer cover.
Knead the dough very well for few minutes.
Apply little oil to the dough and let it rest (covered) for atleast 30-60mins.
Cook sweet potatoes and potatoes in pressure cooker.
Peel them and mash.
Add all the spices, salt and mix well.
Make small balls out of the dough and stuffing (I usually make sure I have equal number of dough and stuffing).
Take a ball of dough and flatten on your palm, use little oil if needed.
Keep a stuffing ball on it and seal the dough properly around the stuffing.
Roll them into paratha. (Do not use too much dry flour).
Roast on hot tava.
Apply ghee from both sides for extra taste (I do that for kids).
Serve hot with yogurt or pickle or any side dish of your choice.
