Heat the olive oil in a large stock pot or Dutch oven over medium heat.
Cook the diced carrots, onions, celery and mushrooms over medium heat for about 3 minutes, until the vegetables have softened.
Add the wild rice, dried herbs and pepper, turkey breast and broth and give it a good stir.
Put the lid on and turn the heat up to medium-high until the soup boils.
Turn the heat down to medium-low and let the soup simmer for about 15 to 20 minutes until the turkey is heated through.
Remove from heat and stir in the ½ cup of fat-free half and half.
