Heat a large pot or dutch oven over medium heat and add a knob of butter or splash of olive oil.
Add the vegetables with the bay leaves and sprigs of thyme then allow to sauté for a few minutes until the veggies start to turn a light golden colour.
Add the chopped garlic and dried oregano and cook for another minute then pour in the chicken broth and orzo.
Stir in the fresh lemon juice and zest then bring to a simmer and allow to boil for 10 minutes until the orzo is tender/al dente.
Add the shredded cooked chicken and cook for another 5-10 minutes.
Season to taste with salt and black pepper and add more lemon juice if needed then serve.
Notes
Feel free to use skinless chicken breasts. Simply poach in the sauce until cooked through then remove, shred and return to the soup.
Add other vegetables like broccoli, fresh spinach, kale or peas to the lemon chicken soup.
