Heat 1 tablespoon neutral oil in a large pot over medium heat. Add the chicken and season with 1 teaspoon of salt and black pepper to taste. Cook for 12 to 15 minutes until completely cooked.
Add the spices:
Season the chicken with 1 tablespoon chili powder, 1 tablespoon cumin, 2 teaspoons garlic powder, 1 teaspoon paprika, and ½ teaspoon cayenne or crushed red pepper. If you like it spicier, add more cayenne or crushed red pepper.
Toss to coat the chicken in the spices and cook until fragrant.
Add the aromatics and vegetables:
Add the minced white parts of the scallions, red onion, and red bell pepper. Toss to coat and cook for 5 minutes.
Add the sweet potatoes and toss to combine.
Simmer the chili:
Add the hot salsa, black beans, and chicken broth. Bring to a boil. Taste the broth and season lightly. It will get saltier as it reduces. Reduce the heat to low and simmer uncovered for 30 minutes, until the sweet potatoes are fork-tender.
Lightly mash a few sweet potatoes with a spoon to create a thicker chili.
To serve:
Spoon the chili into bowls and garnish with the remaining minced scallion greens. Serve with your favorite toppings, such as grated cheese, sour cream, diced avocado, or minced cilantro. Enjoy!
