In a bowl, mix hung curd with finely chopped veggies, coriander leaves, and spices (salt, pepper, chaat masala). Mix well until creamy.
Add a little green chutney or grated paneer for added flavor, if desired.
Use fresh or lightly toasted bread. Trim the edges if preferred.
Evenly spread the curd mixture on one slice. Don’t overfill to avoid sogginess.
Place another slice on top and press gently. You can cut into halves or triangles at this point.
Toast on a tawa with a little butter/ghee or use a sandwich grill for a crispy finish. Or leave it plain for a soft sandwich.
Serve immediately with green chutney or ketchup. Best enjoyed fresh to avoid sogginess.
