In a medium sized pot, on low heat add you olive oil and onions and a sprinkle of sea salt. Allow onions to cook low and slow for 10-15 minutes, caramelizing them. If they start to stick to pot or brown at all add a little water.
Once onions are golden add in your garlic and mix around for 1-2 minutes on low heat.
Add in the can of tomatoes, coconut milk, Italian seasoning, sea salt and pepper, bring to a boil and then cover and reduce heat to simmer.
Let everything cook together for 5-10 minutes, transfer to a blender or use an immersion blender to blend everything together until consistency is nice and creamy. Serve and enjoy!
