In squash season I probably make at least one squash soup a week so variety is crucial. This particular squash recipe includes red lentils to make it a full meal and sumac as the secret ingredient.
If you have never cooked with red lentils before you are missing out, they cook faster then any other legume and have a great nutritional profile. If you like this soup you may also like one of my favorite older recipes for a Butternut squash, red lentil and coconut milk soup.
