Sauté the veggies
Heat (an extra) 1 tablespoon butter or olive oil in a large
stockpot over medium-high heat. Add onion and sauté for 5 minutes, stirring occasionally, until soft and translucent. Stir in the garlic and cook for an additional 1-2 minutes, stirring occasionally, until fragrant.
Add base ingredients
Add in the vegetable stock, wild rice, mushrooms, carrots, celery, sweet potato, bay leaf and Old Bay seasoning. Stir to combine.
Simmer
Continue cooking until the soup reaches a simmer. Then reduce heat to medium-low, cover and
simmer for 30 to 40 minutes until the rice is tender, stirring occasionally.
Add final ingredients
Add the coconut milk and kale to the soup, and stir gently until combined. Taste and season with salt and pepper (plus any extra Old Bay seasoning, if you would like) as needed.
