Channa Chaat is a popular Indian street food made with chickpeas (channa) and a variety of spices and tangy flavors.

Here's a detailed recipe to make Channa Chaat:

Ingredients:
For the Channa (Chickpeas)
1 cup chickpeas, soaked overnight
1/2 tsp salt
Water for boiling

For the Chaat
1 medium onion, finely chopped
1 medium tomato, finely chopped
1 small cucumber, finely chopped
1-2 green chilies, finely chopped (optional)
1/4 cup fresh coriander leaves, finely chopped
1/4 cup fresh mint leaves, finely chopped
1 tsp chaat masala
1/2 tsp roasted cumin powder
1/2 tsp red chili powder (optional)
1 tsp black salt (or regular salt to taste)
1 tsp tamarind chutney
1 tsp green chutney (mint and coriander chutney)
1 tbsp lemon juice
1/2 cup sev (crunchy chickpea noodles)
1/4 cup pomegranate seeds (optional)
1 boiled potato, chopped (optional)

Instructions:

Prepare the Chickpeas:
Rinse the soaked chickpeas thoroughly.
In a pressure cooker, add the chickpeas, salt, and enough water to cover the chickpeas.
Pressure cook for 4-5 whistles or until the chickpeas are soft and cooked through.
Drain the chickpeas and let them cool down.

Prepare the Vegetables:
While the chickpeas are cooling, finely chop the onion, tomato, cucumber, green chilies, coriander leaves, and mint leaves.
If using, boil the potato, peel, and chop it into small cubes.

Mix the Chaat:
In a large mixing bowl, add the cooled chickpeas.
Add the chopped onion, tomato, cucumber, green chilies, coriander, and mint leaves.
If using, add the boiled potato cubes.

Add Spices and Flavors:
Sprinkle chaat masala, roasted cumin powder, red chili powder, and black salt over the mixture.
Add tamarind chutney, green chutney, and lemon juice.
Mix everything gently but thoroughly to combine all the ingredients and flavors.

Serve the Channa Chaat:
Transfer the chaat to serving bowls.
Garnish with sev, pomegranate seeds, and additional chopped coriander leaves if desired.
Serve immediately to enjoy the crunchiness of the sev.

Tips:
Customizations: You can add other ingredients like boiled peanuts, grated carrots, or chopped bell peppers for additional flavors and textures.
Chutneys: Adjust the quantity of tamarind and green chutney according to your taste preference. More chutney will make the chaat tangier and spicier.

Serving: Channa Chaat is best served fresh to retain the crunchiness of the sev. If preparing in advance, mix the sev just before serving.
Enjoy your flavorful and tangy Channa Chaat!
