I like to get chicken when it goes on sale and cook it all up. Then I debone it and freeze it in little baggies and freeze the broth in an ice cube tray and keep them in a big bag. So now I always (er... sometimes!) have chicken and chicken broth handy!
Just boil it for a loooooooong time (I usually go all day)...

Ta-DA!!!! :)
I know, you guys probably already know you can do this... but just thought I should show you how convenient it is!! :)
