Malabar Spinach or Basella is a tropical vine which grows in the tropical regions. This was one green that was used widely at home, simply because it is an annual and was always available in the kitchen garden. Hardly takes any space or effort to grow this green.
Moreover, the english spinach was not always available and was not as popular in the 70's and 80's as it is now, in small towns of South India. Even if spinach is abundantly available now, with the reports of high pesticide content, it is safer to turn to Basella. Nutritionally it is equivalent if not more than the regular spinach.
We typically use it to make a dal or an instant chutney. Yesterday I had some leftover dal and turned it around into a simple paratha and served with a simple curry made of soaked green peas and coconut. A very nutrient dense lunch box option that is finger licking tasty.
