In a heavy bottom pot, add oil.
Let the oil get hot. Once hot add cumin seeds, asafetida(hing) and curry leaves.
Then add minced onions(I used 1 and half onions and pulsed it in a food processor), garlic and green chilies, red chili powder and salt.
Cook the onions by sauteing frequesntly until the oil starts to seperate.
Now add the pureed tomato. I used one Roma tomato and pulse it in the food processor.
Then add, coriander powder, turmeric powder and sev usa masala. Mix everything well and cook until oil separates
Drain the water from the cooked white peas. You can save this water, and add to knead the dough or cook rice. It can make the curry starchy, so we won't be using this water.
Now add the cooked white peas. Mix everything well.
Add 4-5 Cups of Hot water and bring everything to boil.
Check for salt, and add some lemon juice.
Take the oil floating on the top of the curry out, in a bowl.
You can use this, as a topping, like chili oil
Serve it with side of pav, top the curry with sev, red onions and spring onions.
