In a large sauté pan, heat the olive oil for 1 minutes on low heat
Add the chopped onion, raise heat to medium, and sauté for about 5 minutes, until the onion becomes translucent
Add in the broth and peeled potatoes, and let cook at a low boil for 15 minutes, turning the potatoes every so often so they cook all over
Remove from heat and cut potatoes into small chunks
Add in the basil and spinach leaves, cover, and let sit for 5-10 minutes until they wilt
Add in the coconut milk and mix all together
Using a hand-immersion blender or a regular blender, blend the soup well.
Serve or save for up to 3 days.
