Fry till it gets cooked and you see the oil leave the sides.
Now add the cooked and mashed veggies along with chopped capsicum to the cooked masala.
Add in all the dry masalas like pav bhaji masala, both chilli powders and salt. Mix well.
Add water in which the veggies were boiled, stock or some plain water and cook down the bhaji till it is slightly thick.
Taste and adjust seasoning. Use a potato masher to mash down the veggies.
Serve hot garnished with chopped cilantro leaves and butter. Serve onion and lemon slices on the side.
Heat a pan. Apply some butter. Cut the pavs or dinner rolls into halves and toast them on the pan to serve with the bhaji.
Enjoy this delicious treat with your family.
Notes
Do not cook capsicum with the other veggies. I don't like soggy capsicum.Just saute it so that it still stays crunchy.Bottle gourd was what my mum used to add to pav bhaji and you don't really taste it. It adds body to the bhaji. You can easily skip it.You can change the combination of veggies depending upon what is available. According to me potatoes, beans, carrots, capsicum should be there. You can also make your own pav bhaji masala. I use Everest one.
