Once you have made your stock, strain and reserve broth. In a large pot or Dutch oven, heat 2 tablespoons canola oil or other neutral oil over medium heat and add carrots, celery, and onion. Stirring occasionally, let cook and soften for 5 to 7 minutes. Create a circle of veggies and add a little more oil to the center, then add the garlic and let cook for 2 minutes. Stir everything together, then add the fresh stock, shredded chicken, lemon juice, herbs, spices, and salt and pepper. Let simmer for at least 20 minutes so everyone gets to know each other in the pot!
