While the dough is resting, let us make the stuffing.
You need to soak the moong dal in water for at least an hour.
After that, rinse off the dal well and boil it in the pressure cooker until 3-4 whistles or the dal is cooked well.
Once the dal is cooked, mash it with a hand blender or with the help of a spatula.
Now take a frying pan. Add 1 tbsp oil and the mashed moong dal.
Add the spices one by one: turmeric, sugar, salt, cumin & coriander powder, garam masala powder, amchur powder, dry red chili powder.
Sprinkle a little amount of water if you want.
Saute the spices and dal for 4-6 minutes.
After that, turn off the flame and keep it aside.
