Heat your oil in a large stock pot or Dutch oven over medium-high heat.
Add in the onion, carrots, celery and saute for 4-5 minutes.
Stir in the garlic and thyme, then continue to saute for 1 minute.
Add the zucchini, green beans, cooked chicken, and turmeric powder.
Stir in your bone broth and bring to a boil.
Once bubbling, reduce the heat to a low and simmer until the vegetables are tender-crisp, around 12-15 minutes.
Over the last couple of minutes, stir in your chopped kale, lemon zest, and freshly squeezed lemon juice.
Taste and season with sea salt and pepper if desired.
Serve hot with parmesan cheese, if desired.
