Tawa Pav Bhaji is a style of preparing Pav Bhaji on a tawa (griddle) instead of a regular pan. The bhaji is cooked on a tawa along with the pav, giving it a smoky and charred flavor. The vegetables are mashed and cooked on the tawa with the spices and tomato gravy, while the pav is toasted on the same tawa with a little butter. Tawa Pav Bhaji is a popular street food variation that adds an extra dimension of taste to the dish.
