Firstly we will temper Kala Chana in spices.
In a bowl, add all the spices(coriander powder, red chilli powder, kala namak, amchur powder), add 1/4 cup water and mix nicely to make paste.
½ tsp Red Chilli Powder, ½ tsp Amchur Powder, 1 tsp Coriander Powder, ¼ Black Salt, 1 tsp Roasted Cumin Powder
Heat 1-2 tsp oil in a pan. Add cumin seeds. When seeds crackle add the spice paste.
1-2 tsp Mustard Oil, ½ tsp Cumin Seeds
Next, add the boiled chana and mix nicely. Add 1/2 cup chana water/plain water and cook for about 2-3 mins. till the water evaporates.
1 cup Boiled Chana
Take the pan off the flame and cool the chickpeas.
Now in a mixing bowl, add cooked chana, chopped cucumber, tomatoes, onions and herbs and lemon juice. Add salt as required. Be careful as the chana already has salt.
1 Cucumber, 1 medium Tomatoes, 1 medium Onion, Fresh Coriander/Cilantro, Fresh Mint, 1 Lemon
Mix everything nicely and serve.
