In a large soup pot, melt butter (or heat oil) on medium low heat.
Add all the veggies and salt generously. Allow them to cook for 5 - 10 minutes, until softened a bit.
Add the chicken, broth, veggies, and herbs.
Simmer on low for about 2 hours, stirring occasionally.
Remove the chicken from the pot and cut or shred it.
Return the chicken to the pot, taste to adjust salt, then serve.
