Being brought up in India the use of lentils is very common in our home. Therefore, Indian tadka dal (Indian lentil curry) is a staple food in our kitchen. You will find a variety of lentils in our pantry all the time. 

Apart from making classic dal recipes, I love making lentil brown rice salad and whole lentil soups just like this one. No doubt lentils are a great source of proteins in meatless dishes and are perfect for a vegetarian or vegan diet. 

Enough praising LENTILS… Let’s come to our wholesome healthy lentil soup recipe!
