Slow Cooker Chicken Noodle Soup

1 store-bought rotisserie chicken carcass, or 1 1/2 cups already cooked chicken meat
6 cups water
1 or 2 sweet potatoes, peeled and chunked
2 teaspoons chicken bouillon granules (check for gluten, this was clearly labeled gluten free)
1 cup broccoli florets
1 small onion, diced
1 tablespoon, plus 1 teaspoon balsamic vinegar
kosher salt to taste (probably a good 1 teaspoon, since the base is water)
50-cent piece size, or so, handful of raw spaghetti noodles to add at the end (I used Trader Joe's brown rice)
1 large handful raw spinach leaves to add at the end
Parmesan and Asiago cheese, optional garnish

The Directions.

If you're going to use a chicken carcass, cook it on low overnight in the water. In the morning, unplug the crock and let it cool before digging in with CLEAN hands to pick out the bones. Strain through a colander (retaining liquid!) if desired.
Or, start with a slow cooker with 6 cups of water, and add chicken. Add all vegetables except for the spinach leaves. Stir in the bouillon and vinegar. Salt to taste. Cover and cook on low for 7-8 hours, or until sweet potatoes are tender and the onion is translucent. (I forgot about starting it until 2, and so I turned it to high for about 3 hours and it was just fine)

15 minutes before serving, put in raw spaghetti noodles and a large handful of spinach. Cover and flip to high.

Garnish with parmesan and asiago cheeses, if desired.
