01 - In a large pot or Dutch oven, heat 1 tablespoon olive oil over medium heat. Add the chicken pieces and sauté for 3-4 minutes, until just cooked through. Remove chicken and set aside.
02 - Add a little more oil to the pot if needed, then add the diced onion, carrots, and celery. Cook for 5 minutes, stirring occasionally, until softened.
03 - Stir in the minced garlic and cook for 1 minute, until fragrant.
04 - Add the cubed potatoes, green beans, corn, chicken broth, bay leaf, thyme, parsley, black pepper, and salt to the pot. Bring the mixture to a boil.
05 - Reduce the heat to a simmer, cover the pot, and cook for 15 minutes, or until the vegetables are tender.
06 - Return the cooked chicken to the pot and continue to simmer for another 5 minutes, ensuring it is heated through.
07 - Carefully remove and discard the bay leaf. Taste the soup and adjust the seasoning as needed with additional salt or pepper.
08 - Ladle the hot soup into bowls. Garnish with fresh chopped parsley and a squeeze of lemon juice, if desired, before serving immediately.
