Grab a soup pot and add a tablespoon of olive oil. Put the pot over medium heat on the stove.
Now add the chopped veggies to the pot: celery, carrots, garlic, and onion. Sauté for a minute or two and then add in all the seasonings: dried parsley, dried dill, Italian seasoning, salt and pepper. Sauté for about five more minutes to allow the veggies to soften.
Next, push the veggies to one side of the pan and add a drizzle of olive oil to the other side. Add in the chicken breast. Cook for about 2-3 minutes on each side until seared and browned.
Now add in the chicken broth and bring the soup to a boil. Let the soup with the chicken boil for ten minutes. Then add in the uncooked orzo and let the soup boil for another ten minutes or until the chicken breast is cooked through and reaches 165 degrees F. This can take varying amounts of time depending on the size and thickness of the chicken.
Using tongs, remove the cooked chicken from the soup and chop it up with a knife on a cutting board. Add the chicken back to the soup and stir to combine.
Lastly, zest and juice one lemon and add it to the soup. Stir to combine. Serve the soup warm in large soup bowls and enjoy! (If you like more seasonings, stir in more parsley, dill, salt and pepper. You may need to add more seasonings depending on what type of chicken broth you use)
