Roast the Veggies: Begin by roasting the green chillies (with their stalks) and the deseeded large tomato on a hot iron skillet (tawa) until they develop a slight char.
Blend Coarsely: In a mixer jar, add the raw mango pieces, roasted green chillies, and the roasted tomato. Pulse your mixer just once to get a coarse, chunky texture. Do not make a smooth paste!
Prep the Base: In a mixing bowl, add your chopped medium onion. Make sure the pieces aren't too big or too small.
Combine Ingredients: Transfer the coarsely ground raw mango and tomato mixture into the bowl with the chopped onions.
Add the Spices: Add the red chilli powder, chaat masala, black salt, regular salt, and a handful of fresh coriander leaves to the bowl.
Mix and Serve: Mix everything thoroughly so the onions are well-coated with the dry spices and the tangy mango paste. Your Spicy Raw Mango Side Dish Recipe is ready!
