Related: if you ever get a $5 Costco rotisserie chicken, don't throw it away when you're done with it! Put the rest in a small pot with some water and let it barely simmer for a long time (6-12 hours). Taste it every few hours, adding salt and stirring. Strain out the bones and other gunk, and you'll end up with delicious mostly-homemade chicken broth.
