Add the oil and onion to a soup pot and saut? over medium-high heat for 5 minutes.

Add all the remaining soup ingredients to the pot except for the cream cheese, chicken, and salt & pepper.

Increase the heat to high and bring the soup to a boil. Turn down the heat so it's simmering gently (uncovered) for 5 minutes. While the soup cooks, prep your toppings.

Cut the cream cheese into smaller pieces and add it to the soup. Let it melt in, stirring until fully incorporated.

Stir in the chicken and cook for another 5-7 minutes or until warmed through.

Season the soup with salt & pepper and serve with toppings as desired.
