Set a large 6-8 quart soup pot on the stovetop over medium heat. Add the butter. Once melted, add the chopped onion, red bell pepper, green bell pepper, and garlic. Sauté the vegetables for 3 to 4 minutes to soften.
Add in the drained black beans, Rotel, frozen corn, taco seasoning packets, and broth. Stir and simmer for 10 minutes.
Finally add in the cream cheese and shredded chicken. Stir until the cream cheese melts into the soup base making it slightly creamy.
Serve warm with your favorite taco toppings.
