Use your favorite soup pot, approximately 6 quart size.
Heat enough olive oil to coat the bottom of your pan over medium high heat.
Once barely smoking, add your onions, carrots and celery, cook till soft approximately 8-10 minutes.
Once veggies are soft, add the minced garlic and bay leaves, cook for about 1 to 2 minutes.
Then add chicken stock and bouillon, bring to a boil.
Add pastina and cook for 5 minutes, remove from heat add in your cooked chicken and parsley.
Now, you're ready to eat, I like to squeeze a little lemon and add some pecorino romano or parmesan on the soup.
