This hearty soup is a great way to use your food processor to make a delicious and healthy meal. Start by processing some cooked rice until it is finely chopped. Then, add in some cooked lentils and pulse until they are roughly chopped. In a pot, sauté some chopped vegetables, such as onion, celery, and carrots, until they are tender. Add in the rice and lentils, along with some vegetable broth and your favorite seasonings, and simmer everything together until it is hot and flavorful. This soup is perfect for a cold winter day or for meal prep for the week ahead.
