Do the same with lentils. Blend lentils with 1 cup filtered water in a blender until very smooth.
Combine the rice and lentil batter into a large ceramic or glass bowl, add salt, mix well.
Cover the batter and leave for 8-10 hours, or overnight, to allow fermentation.
Prepare desired vegetables or toppings before cooking.
Preheat a non-stick frying pan to medium heat and lightly grease with vegetable oil.
Pour the batter into the pan to make a thick pancake, about 5-10mm.
Immediately top with your favorite vegetables and toppings, then cover the pan with a lid.
Cook for about 2 minutes on one side, then about 1 minute on the other side, until the batter is cooked well. If there are a lot of toppings and flipping is not possible you may cook for 2-3 minutes on one side only.
For toppings you can use a variety of vegetables, such as onion, red onion, chives, bell pepper, tomatoes, grated carrots, corn, green beans, coconut, etc.
Serve with chutneys of your choice.
