In a large skillet with a lid, heat the oil over medium heat. Add in the onions and garlic and cook for 3-4 minutes until the onions begin to turn clear.

Add in the Italian sausage slices and turn the heat up slightly (just above medium). Cook 10-12 minutes until all of the slices are browned on the outside and the sausages are mostly cooked through.

Add in the canned tomatoes, tomato sauce, water, basil and salt. Stir well. Mix in the noodles and cover. Within 1-2 minutes the mixture should be covered and boiling slightly. Cook at a small boil for 10 minutes.

Uncover and stir. Leave the lid off and cook for another 12-15 minutes or until noodles are tender. If you find the sauce getting too thick, add in 1/8 cup of water and keep at a boil. In the meantime, chop your spinach.

Once the noodles are tender, stir in the coconut milk, parmesan, and spinach. Turn off the heat.

Let sit for 3-5 more minutes for the sauce to turn creamy.
