In a large mixing bowl take 2 cups of sattu (roasted gram flour) and add 1 tbsp of finely chopped green chilies, 2 tbsp of garlic, 1/3 cup of onion, 1 tbsp of ginger, 3 tbsp of coriander leaves, 1 tbsp of lemon juice, 1 tsp of carom seeds (ajwain), ½ tsp of nigella seeds (kalonji or kala jeera), 1 tbsp of pickle (mango or mixed pickle), and 2 tbsp of mustard oil. Also add salt to taste and mix them all very nicely. Keep it aside.
In a separate bowl, take 2 cups of wheat flour (atta) and mix ½ tsp of salt with it. Then add water gradually as required to make a soft dough. Cover the bowl with a plate and let it rest for about 15 minutes.
Make relatively large dough balls. Press with your fingers in a circular motion to shape it like a bowl. Put 2 to 3 tbsp of sattu stuffing in it.
Now, press the sattu stuffing with your fingers. Bring the ends closer by moving it in circular motion. Seal it properly.
Heat a tawa over a medium flame. In the meantime, roll it to make a relatively thick paratha, pressing it gently and evenly on all sides to spread the sattu stuffing evenly inside.
Put the paratha on the preheated tawa. Flip it after 20 seconds. Apply ghee or cooking oil on the surface. Flip again. Grease the other surface with ghee.
Flip it a couple of times until both sides are nicely cooked and turn golden brown. Remove when done.
Your tasty and crispy homemade sattu paratha is ready to enjoy. Serve them hot with tomato chutney, plain or spiced curd.
