Yesterday on Diwali,I made this moong dal vada. It was relatively easy compared to urad dal vada i soaking time and frying time. Soak 2 cups of moong dal for half an hour and grind to a coarse paste using water.Add 1 tbsp of rice flour. Add ginger - green chillies and jeera paste. Add chopped onions. Season with required salt and mix everything to form a thick vada batter.Take a small lemon sized ball and press with fingers to form a flat patty and carefully drop into hot oil and fry both sides till golden and drain onto a paper towel.
