Drain the potatoes and then add them to the pot, along with the chicken broth, oregano, salt, and pepper, and the bay leaf. Bring to a boil (about 5 minutes), then cover and simmer on the lowest heat setting for 10-15 minutes, until the potatoes are fork tender.

To a small mixing bowl or measuring cup, add the milk and cornstarch. Whisk together until dissolved, then slowly whisk into the soup. Add the shredded chicken to the soup. Turn the heat back up to medium-high and bring back to a soft boil, stirring as the soup thickens, then cook for another 5 minutes.
