Sub squash soup for tomato sauce on pasta

Oh god I love tomatoes but my body hates them (they are one of my worst migraine and GI triggers). I had a jar of butternut squash soup from world market in the pantry and just used that one night on a whim when I was craving pasta. It was SO good. I’ve since done this with my dad and his friend who are picky eaters. Just served it up without saying anything. They didn’t notice anything out of the ordinary and ate the whole pot.
