Step 1

Heat the olive oil in a large pot over medium heat. Add the onions, garlic, carrots and celery. Sauté, stirring frequently for about 5-6 minutes.

Step 2

Add the red lentils, broth, cumin, coriander and turmeric and stir to combine. Bring to a boil, then lower heat to a simmer for 30 minutes, until the lentils are soft.

Step 3

Place the cashews and lemon juice in a high powered blender, along with 2 cups of the soup. Blend on high until creamy and smooth.

Step 4

Add the creamy blended mixture back to the pot and stir in the spinach/kale, if using. Cook for a few minutes until kale has softened, if using.  If you want a thinner soup, add 1/2-1 cup of water or more broth.

Step 5

Taste and add salt/pepper and cayenne pepper. Serve immediately and enjoy!

Step 6

Leftover soup will keep for 4-5 days in the refrigerator, and can also be frozen. It does thicken as it sits, so add a little water or broth when you reheat it. It's also good served with a scoop of rice.
