Pour lentils into a pot.
Add water and salt. Bring heat up to medium high.
Heat lentils and stir, then add skin and wing tips. Cook for another 15 minutes. Reduce heat to medium low.
Then add your chicken juice.
Cook for another 15 minutes.
Scoop out all the loose chicken parts.
Now add your pesto and pasta water
Continue to cook for another 15 minutes the lentils will break down and become creamy.
Stir to avoid the lentils sticking to the bottom.
Cook on low until the soup is creamy and smooth. You want to make sure you don't under cook the lentils, since you're making a soup you can't really overcook this. If you want the soup to be ultra creamy, pour the soup (in batches) into a blender.
Enjoy with a nice piece of crusty bread, or freeze the soup for later, it keeps well in the freezer for a few months at minimum.
