Finely chop onion and tomato and coriander leaves.
Mix corn pearls, onion, tomato, chaat masala, red chili powder and coriander leaves.
Squeeze a lemon just before serving and serve.
Notes
Let the corn cool completely before mixing tomato and onion otherwise the heat from the corn will cook the onion and tomato. In this dish we want the raw taste of onion and tomato.You can substitute chopped green chilies instead of red chili powder.
