This simplified scratch-made soup is a spicy (but not too spicy) step beyond basic chicken soup. Made with chili powder, cumin, green chiles, corn and tomatoes, there’s plenty of flavor to go around. Add rice toward the end of cooking to keep the texture just right, and when it’s good and hot, serve with crunchy tortilla chips and a helping of shredded Mexican cheese blend for a hearty, satisfying meal in a bowl.
