Place 2 diced boneless chicken breasts into the crock pot.
Add 6 cups chicken broth, ½ diced onion, 2 diced celery stalks, 2 peeled and diced carrots, 2 teaspoons minced garlic, 1 can diced tomatoes with green chiles, and 1 seeded and diced jalapeño pepper.
Stir in 1 teaspoon cumin, 1 teaspoon ground coriander, ½ teaspoon salt, and ½ teaspoon black pepper.
Cover and cook on low for 5–6 hours or on high for 2½–3 hours until the chicken is fully cooked and the vegetables are tender.
Stir in 2 tablespoons chopped fresh cilantro right before serving.
