Repeating what @coolmidwestguy said, I love butternut squash soup, especially in the winter, it's so comforting.
I'm sorry to hear about your brother's condition, hopefully he will find plenty of recipes to suit his diet, and I'm sure with your help, he will.
I'd forgotten about this soup, I usually make thick broths during winter, but my younger brother bought him some heat and eat soups. Their butternut squash soup is good, but nothing beats homemade.
He's very fortunate to have beaten the throat cancer, it was Stage 4 already; could pop up elsewhere? He lives alone which is a concern because of the choking risk. And, still smokes, but won't listen!!!
