Sama ke chawal are also known as barnyard millet or samo/moraiyo. This kheer is especially made during fasts/vrat. Sama rice gives the same texture and feel as the normal rice. But, they are more healthy as compared to rice in many ways :
high on calcium, potassium, phosphorus and amino acids
rich source of vitamins and minerals
contains high digestible fiber
You can substitute this grain in many dishes that contains rice, like pulao and khichdi. This also has a texture similar to that of sooji/rava/semolina. So just as you make upma, you can add in your favourite veggies and make vegetable samak rice upma/pulao.
