Delicious Usal is ready
To use the same gravy, and turn it to Missal:
In a bowl, take the Usal. Garnish it with chopped onions, chopped cilantro, Sev/ Bhujia and serve with pav (Indian Dinner Rolls / Indian bread) . Few also add Tharri (a thick spicy gravy on top of the usal, but that's a personal preference)
