Heat 1 tablespoon neutral oil in a large pot over medium heat. Add the turkey and season with chili powder, cumin, garlic powder, ground coriander, cayenne powder, 1 teaspoon salt, and ½ teaspoon black pepper. Toss to coat and cook for 12 to 15 minutes until the turkey is cooked through.
Cook the aromatics:
Add the jalapeño, bell pepper, and onion to the turkey. Season with ½ teaspoon salt and more black pepper to taste. Cook for 5 to 7 minutes, turning occasionally, until the peppers and onions soften.
Simmer the soup:
Add the black beans, enchilada sauce, crushed tomatoes, and chicken stock. Bring to a boil. Reduce the heat to low and add the corn. Simmer, uncovered, for 30 minutes. Taste and add more salt, pepper, or seasonings to your preference.
To serve:
Ladle the soup into bowls and garnish with minced cilantro, sour cream, and slices of jalapeño if you like. Enjoy!
