Add chickpeas, onion, garlic, avocado oil, parsley/coriander, lemon juice, cumin, salt into a food processor and pulse until just combined.
Pulse it in such a way that the mixture is neither too smooth in consistency as having a few chunks of chickpeas gives the falafel a nice texture.
Add sattu flour.
At this point, your mixture should be holding together quite well.
Take a few spoonfuls of mixture out and form into small patties.
You can grease the tawa with few drops of oil and pan fry the patties till golden brown.
or
Bake for 10-12 minutes at 250 degrees and flip patties and bake for another 10-12 minutes or until the falafel until falafel is golden and cooked.
