Creamy Chicken Orzo Soup

I'm surrounded at work by sick people.  Don't get me wrong, they are very lovely people but two types of flu and colds are working their way through the building.  I made soup tonight to help my hand sanitizer and the one multi-vitamin that I took to ward off the evil.  

Creamy Chicken Orzo Soup

3 tbsp extra virgin olive oil
3 chicken breasts, cubed
1/8 cup onion, diced
3 cloves garlic, minced
6 cups chicken broth
1 1/2 cups carrots, sliced and diced
1 tbsp celery flakes
1 bay leaf
2 dashes hot sauce
1 1/2 cups milk
1/2 cup peas
1 cup orzo pasta
1 tbsp parsley
salt and freshly ground pepper to taste

Heat olive oil in the bottom of a large pot or dutch oven.  Add in chicken and heat until no longer pink (do not cook long enough to get a crust).  When almost cooked through, add in onions and garlic and cook until translucent.  Pour in chicken broth and add in carrots, celery flakes, bay leaf and hot sauce.    Cook over medium heat until carrots are tender and add in milk, orzo, peas and parsley and cook for an additional 10 minutes.
