In a soup pot, heat the olive oil on medium high. Add the sliced mushrooms, onions and garlic. Saute until the mushrooms and onions are cooked, about 3-5 minutes. The onions should be translucent. Season with salt and pepper.
Now add the sherry, and stir to get any bits off the bottom of the pot. Then add the tomato paste. Stir into the mushrooms and onions.
Now add the veggie broth and coconut milk. Stir to combine. Taste and add a bit of salt and pepper to taste. Bring to a boil.
Now add the noodles, reduce the heat a bit and simmer until the noodles are cooked al dente. Check the package instructions for how long that will probably be according to the type of noodles you have.
Taste and season as needed. Serve immediately!
