Wash and soak your whole moong beans and rice together in water for at least 4 hours.
Drain your soaked moong and rice, and add them to a blender along with the green chili, ginger, and a splash of water.
Blend until completely smooth and pourable, then transfer to a bowl and season with salt to taste.
Heat a flat pan or cast-iron tawa over medium-high heat and lightly oil or ghee the surface.
Pour a ladleful of the batter into the center and use the back of your ladle to spread it outward in circular motions into a thin, even layer.
Drizzle a few drops of oil or ghee around the edges and center, cooking until the bottom turns golden-brown and crispy.
Fold or roll it up and serve piping hot!
