Instructions
- Heat oil in a large stockpot over moderate heat. Add onion, garlic, carrots, celery, and bell pepper and stir. Season with salt and pepper and stir until the veggies start to soften.
- Add sweet potatoes, bay leaf, thyme, soup base, and water, and bring to a boil.
- Add lentils and Parmesan rind and reduce heat. Simmer until sweet potatoes are fork-tender, about 20 minutes. Stir in spinach and continue to simmer for an additional 5 minutes.
- Remove bay leaf, thyme sprigs, and Parmesan rind. Taste for seasoning and adjust if necessary.
- Serve warm, preferably with some nice, crusty bread for soaking up all of the goodness.
