Pulicha Keerai or Gongura leaves are very famous in Andra Pradesh (South India). If you want spicy spicy side dish to go with rice, then this thokku should be your choice. You can even call it as chutney, where you can pair it with dosa varieties.
Ulundhu vadai/ medhu vadai is the best combo for pongal. Whenever i do pongal my first thing to do is soak a cup of urud dhal. It is easy to make, crispy and also soft inside and not to forget a hole in the center. It is purely a southindian dish.
