Place a medium-sized heavy bottomed pan (I use this 6 qt stockpot) on high flame and add water, lentils, cumin powder, turmeric powder, red pepper chili flakes, onion slices and garlic clove. When it comes to a boil, turn the flame down to medium Cover with lid, but not completely, so as to allow some steam to escape, otherwise the lentils will overflow onto your stovetop
Allow lentils to simmer for 20 minutes, stirring every 5-7 minutes to make sure the lentils are not catching at the bottom of the bottom. You may have to top the lentils up with hot water to loosen it, if it looks too thick. Alternatively, if it looks too thin, allow it to cook down some more
When the lentils are ready, they will look creamy
Smoosh the garlic clove with the back of your ladle, it will blend right in
Add kale and stir gently
Serve with a trail of your favourite olive oil, scatter some sumac, pul biber (also known as crushed Aleppo pepper) or red cayenne pepper on top For a non-vegan version, add a dollop of Greek yoghurt
