Heat a pan and dry roast the rolled oats on low heat for 3–4 minutes until they give out a nutty aroma.
Let them cool, then grind into a fine powder.
In a blender, add the sprouted moong, green chillies, and ginger. Blend into a smooth paste using a little water if needed.
Transfer this paste to a mixingbowl.
To the moong paste, add the oats powder, chopped onion, grated carrots,coriander leaves, ajwain, turmeric powder, red chilli powder, and salt. Mix well. Add about ½ cup water to get a thick, spreadable batter.
Let the batter rest for 30 minutes to allow the flavors to blend. Add more water if required to adjust the consistency of the batter.
Heat an iron skillet . Pour a ladleful of batter and spread it gently in a circular motion to form a cheela.
Drizzle a little oil around the edges.
Cover and cook on low heat till the underside is golden.
Flip and cook the other side till done.
Serve hot with green chutney.
