Quick Pumpkin Soup

This soup is from my mom, who got it from Aunt Cheryl, who got it from a lady who, I am told, wanted, to devise a few meals that would require virtually no preparation.

1 can pumpkin or pumpkin pie mix (depending on whether you like it sweet or not, you can add pumpkin pie spice to taste if you are using the plain stuff)
1 can white beans
1 can coconut milk
1 can chicken broth
1 tsp sage

Mix, heat, and serve. If you want smoother soup, puree the beans before adding.
