Begin by chopping your bell peppers into small, colorful pieces, and tear the tortillas into uneven strips to help them soften faster.
Place the chicken pieces into the slow cooker, then add the diced tomatoes, chopped bell peppers, cumin, chili powder, and chicken broth.
Gently stir everything together, ensuring the spices and vegetables are evenly distributed around the chicken. Cover with the lid and cook on low for 6-8 hours or high for 4-5 hours until the chicken is tender and shreds easily.
Once cooked, carefully remove the chicken and shred it with two forks, then return the shredded chicken to the soup. Stir gently to combine.
Add freshly squeezed lime juice to the soup, stirring well to brighten and balance the smoky flavors. Taste and adjust seasoning if needed.
Ladle the hot soup into bowls, then garnish with chopped cilantro, shredded cheese, and crispy tortilla strips for texture.
Serve immediately while steaming hot, with extra lime wedges and tortilla chips on the side for added crunch and zest.
