Notes
Chicken: If you prefer dark meat, use boneless skinless chicken thighs. You can substitute already cooked chicken (like rotisserie chicken or Instant Pot shredded chicken); add it to the chili when you add the beans. The nutrition information is calculated for 2 pounds boneless skinless chicken breasts.
Jerk seasoning: Jerk seasoning can vary in spiciness from brand to brand, so if you're unfamiliar with it, try using a lesser amount at first to make sure it isn't too spicy for you. You can also add more/less hot pepper sauce.
Bean choices: If desired, substitute a different type of bean: pinto, black, or navy beans are good choices.
Storage/reheating: Stored properly, leftovers will last for three to four days in the fridge, or freeze the chili in freezer safe storage containers for up to 3 months. Thaw overnight in the refrigerator for best results. To reheat, put the chili into a saucepan over low to medium heat until warmed through or gently reheat individual portions in the microwave.
