We have been looking for more vegetarian options so I thought I would try this out. I put my food processor to work doing all the mincing. The original recipe called for carrots, but we had run out so I substituted sweet potato. Their sweetness was a great balance to all the strong flavor from the cardamon and cumin.
I made my food processor do all the work for this recipe. I threw in the onion, garlic, and peeled ginger and diced them all at once. Then sauteed it all in olive oil.
Then I diced the sweet potato and celery in the food processor too.
I placed the beans, lentils, tomatoes, water, sweet potato, celery, cardamom, cayenne, cumin, and sauteed onion, garlic, and ginger into the slow cooker for about 4 hours on high or 8 on low. Cook until the lentils are soft.
