Bring a drizzle of neutral vegetable oil (like avocado) to medium heat in a pot. Add in the diced onion, and sauté for about 5-7 minutes, or until onion is softened.
Then, add in the garlic, and sauté for another 30 seconds, or until fragrant.
Then, add in the kale and sauté for another minute, until kale is softened.
Then add in all other soup ingredients and stir well until everything is combined.
Simmer soup for about 15-20 minutes, or until red lentils are completely soft.
Taste, and adjust seasonings if necessary.
Serve with fresh parsley and pumpkin seeds, if you'd like.
