In a big bowl take all the flours. Add finely chopped onions, green chili paste, chopped coriander, sesame seeds, groundnut, coriander powder, cumin powder, red chili powder, and salt and mix well.
Add warm water to the bowl and knead it into a soft dough. The dough will be slightly sticky because of the combination of various flours.
Grease a plastic sheet and take a small orange sized ball and pat it to form a 4-5" diameter disc of 1/2" thickness. You need to wet your hands for easy spreading. Slightly press the edges with your fingers to give a nice circle. Once the disc is formed, with your fingers make few holes with equal spacing on the top. This helps in drizzling oil into the holes to help cook evenly.
Transfer it carefully onto a hot tawa and pour oil in the holes and also around the edges and cover it with a lid. You can smear some water on top of the thalipeeth, this will make sure that the thalipeeth would not get dry.
Let it roast on a medium flame for 2-3 mins, once it is brown at the edges turn to the other side and roast again.
Repeat the same for the remaining dough to make thalipeeth.
Serve it hot with Thecha, Mango Pickle, and salad.
