How about a bubbling cauldron of witches' brew stew for Halloween dinner? With black lentils and green spinach leaves, this nutrient-packed and surprisingly delicious Halloween soup looks like something straight out of a Halloween horror movie!
Add the olive oil to a 4 or 5-quart pot over medium heat. Add the onion and celery, and cook until starting to soften but not brown, about 7 minutes. Add the garlic and cook 1 minute more, stirring constantly.
Add the vegetable stock, lentils, bay leaf, salt, and black pepper. Bring up to a boil, and then cover the pot, turn the heat down to simmer, and cook until the lentils are tender, about 20 minutes, stirring occasionally.
Stir in the spinach, parsley, chives, and thyme, and cook until wilted, about 2 minutes. Stir in the lemon juice.
Serve garnished with more fresh herbs.

Notes
Storage and Freezing: Once this soup is cooled, you can store it in an airtight container in the fridge for up to 4 days or in the freezer for up to 3 months.
Cooking Time: The cooking time for lentils can vary quite a bit depending on a few different factors, such as how old the lentils are, the weather, lentil size, etc. I like to start checking to see if they're tender around the 15-minute mark. If you overcook lentils they'll still taste fine, but they will lose their shape, turn mushy, and thicken the soup for a thick, creamy consistency instead of a brothy texture.
Spice it Up: For more complex flavor, add 1 teaspoon ground cumin and/or coriander. And if you like spicy heat, add a pinch of crushed red pepper flakes on top when serving.
