Pressure cook soaked legumes with little salt till they turn soft, I cooked for 3 whistles and simmered for about 5 minutes. Let the pressure subside naturally.
Meanwhile heat a cooking pan and add oil. When the oil gets heated up add cumin seeds and curry leaves. As the cumin starts spluttering include chopped onions. Saute them till they turn translucent.
Throw the crushed ginger, garlic too for sauteing. Continue stirring and add chopped tomatoes. Cook them together till the tomatoes turn soft and pulpy. At that stage you need to mix in all spice powders(turmeric, red chilly, garam masala, coriander powder and salt). Combine well.
Finally include cooked black eyed peas along with it's water. Combining everything together, smash some of the legumes using back of the ladle so that the gravy becomes thick. Let the masala boil for a while and switch off the flame. Garnish it with chopped coriander leaves.
