Place butternut squash, red lentils, red onion, garlic, jalapeno, ginger, curry paste, herbs, sea salt, light coconut milk, and 4 cups of water in a large pot and bring to a boil.
Lower heat and allow the soup to simmer, uncovered, for 20-25 minutes, until the lentils and squash are very tender.
Add tamari and lime juice.
Remove the pot from heat. Either use an immersion blender or transfer the soup to a blender in batches, and blend until smooth. If the soup is too thick, add water to reach a creamy soup consistency.
Taste and adjust seasonings to your liking.
Stir in cilantro. Enjoy!
