Stir in the ginger-garlic paste and mix well. Cook till onion are translucent.
Add the tomatoes followed by salt and pepper. Mix well, cover and cook till the tomatoes are soft and juicy. Stir intermittently.
To this add the red and green bell pepper and cook for a min. These taste best when they still have some crunch so don't cook them fully.
Stir in the spices - Pav bhaji masala and red chili powder. Give it a good mix and cook for another minute for the masala to cook.
Add the boiled veggies like green peas, corn, carrot, and beans. Mix well and cook for a minute allowing these veggies to soak the masala.
Stir in the cooked rice. Mix well so that everything gets well incorporated.
Finally, add the lemon juice and coriander leaves and give it a final stir.
