Soak chana dal in 2 cups of water for about 2 hours. Drain the water and add the lentils to a blender or food processor. Reserve 2tbsp of lentils.

Add green chilies, ginger, garlic (if using), salt and blend to form a coarse paste. Try not to add any water while grinding. If the blade is stuck, then just sprinkle a few drops of water.

Remove the lentil paste into a medium size bowl. Add chopped spinach, onions, cilantro, curry leaves and mint (if using). Mix well to combine.

Heat oil in a small wok or a saucepan on medium heat. Take a small size ball of the lentil mixture and flatten it lightly on your palm. Gently slide it into the hot oil. Depending on the size of the pan, 4~6 fritters/ vada can be fried at a time. Cook on medium flame, turning the vada occasionally to cook evenly on both sides. Fry until golden brown on both sides, about 2 minutes per side.

Using a slotted spoon, remove the fritters/ vada on to a paper towel lined plate. Repeat with the remaining lentil mixture.

Serve vada hot with mint chutney or ketchup and Enjoy!!
