How to Make It
Soak Chana Dal in water for 30 minutes. Drain and rinse until water runs clear. Set aside.
Select SAUTE setting on an Instant Pot. Select HIGH temperature setting, and allow to preheat. Add olive oil. Add cumin seeds; cook, stirring often, until lightly toasted and aromatic, 3 minutes. Stir in onion, bell pepper, ginger, and garlic, and cook 2 minutes. Add tomatoes, curry, coriander, turmeric, and 1 teaspoon of the salt, and cook 1 minute. Add chana dal and stock; lock lid in place. Turn steam release handle to SEALING position. Select MANUAL/PRESSURE COOK setting. Select HIGH pressure for 14 minutes. (It will take 10 to 15 minutes for cooker to come up to pressure before cooking begins).
Carefully turn steam release handle to VENTING position, and let steam fully escape (this will take 2 to 3 minutes). Meanwhile stir together yogurt, cilantro, lime juice, and remaining 1/4 teaspoon salt.
Remove lid from cooker. Top each serving of Chana Dal with a dollop of yogurt sauce.
