Sauté Aromatics: Heat the extra virgin olive oil in a large stockpot or Dutch oven over medium heat. Sauté the diced onion and bell pepper for 5 to 6 minutes until softened. Add the minced garlic and cook for 1 minute until highly fragrant.
Bloom Spices: Stir the taco seasoning, ground cumin, chili powder, smoked paprika, and dried oregano directly into the vegetables for 30 seconds to bloom the dry spices.
Combine Ingredients: Place the raw chicken breasts into the pot. Pour in the low-sodium chicken broth, fire-roasted diced tomatoes, rinsed black beans, kidney beans, and sweet corn. Stir thoroughly to combine all ingredients.
Simmer: Bring the mixture to a boil over medium-high heat. Once boiling, reduce the heat to low, cover with a lid, and simmer gently for 20 to 25 minutes until the chicken registers an internal temperature of 165°F.
Shred Chicken: Carefully remove the chicken breasts from the pot using tongs and place them on a cutting board. Shred the meat into bite-sized pieces using two forks.
Finish and Serve: Return the shredded chicken back to the pot. Stir well and let simmer uncovered for an additional 5 minutes to allow the chicken to absorb the rich broth. Remove from heat, squeeze in fresh lime juice, ladle into bowls, and serve with your choice of healthy toppings.
