A wide range of spices and herbs are usually available for bean soups, e.g. savory, lovage, rosemary, bay leaf, but also paprika powder or chili, and that was just a small excerpt. The spices vary depending on the method of preparation. But the only spices that actually go in here are salt and pepper, and veggie broth. I've been making this myself for years, and I'd like to share my recipe for it here soon.
