Roast Murmura in a wide pan in two batches on medium heat for 5 to 7 minutes each or until it is hot to the touch. You can also try to break a few with your nail and you will hear the crunch.
Rough chop half of the curry leaves and reserve along with the whole leaves.
Add ginger and green chilies to a grinder jar and grind coarsely.
Add 2 tablespoons of oil to the pan. Add peanuts and fry on medium heat for 3 to 4 minutes or until the peanuts are lightly browned. Using a slotted spoon take out fried peanuts leaving any excess oil in the pan and reserve the peanuts.
Add roasted chana dal to the pan and roast for 3 to 4 minutes or until the chana dal is lightly golden. Take out the chana dal using a slotted spoon leaving all excess oil in the pan. Reserve the chana dal with the peanuts and murmura.
Add the remaining oil to the pan and heat. Add asafetida and mustard seeds. Once the mustard seeds start to pop turn the heat to the lowest. Add turmeric, sesame seeds, curry leaves, ginger, and green chilies to the pan. Saute for one to two minutes on low heat making sure the chiles and ginger do not brown. Turn the heat off. Add to the roasted Murmura with the peanuts and roasted chana dal.
Add salt and sugar. Gently mix it all.
Allow the Chivda to completely cool down. store in a dry air-tight container at room temperature for 3 to 4 weeks.

Notes
Sift the Murmura and discard the small particles before roasting
Coarsely grinding ginger and chilies, and chopping some of the curry leaves make the Chivda more flavorful than just adding pieces
Fry the ground chilies, ginger, and curry leaves on low heat for a crispy texture
Peanuts and chana daal can also be baked or air-fried if you like
