Wash and Soak the Brown Lentils in enough water for at least 2 hours. (One can use canned brown lentils too but be sure to wash them before using)
In a large pan add the oil. Once it is a bit hot, add in the chopped onion and garlic.
Saute for 1-2 mins until translucent.
Add in the chopped vegetables. Let them cook for 3-4 minutes.
Next add in the Tomato puree, and lentils, smoked paprika, black pepper, salt, soya sauce, green chillies.
Mix everything and let it cook for 15-20 mins on medium stirring in between until the sauce thickens.
You should be able to get a nice thick lentil and vegetable mix.
