Finely chop or grate raw mangoes.Add them to bowl.
I generally soak onions for 15 minutes before adding to any salad to reduce the overpowering taste of onions. Soak it for 10-15 minutes. Strain excess water and add onions to bowl
Add cilantro and celery to mangoes. If you dislike celery, replace it with parsley
Mix soy sauce, brown sugar, red chilli flakes, lemon juice, cumin powder, salt and paprika in a bowl. The quantity can be adjusted as per spice and sweet level desired
Add this mixture to veggies and toss well until well coated
Cover and rest aside for 30 minutes. This will allow flavours to set in. The longer it rests the better is the flavour of salad.
Garnish with cilantro. Serve as is or with steamed rice
