In a large skillet, heat oil over medium heat. Chop up jalapeño and onion and add to the skillet. Allow to cook 6-8 minutes or until tender.Add garlic and corn and cook one minute longer.Mix in chicken, chili powder, cumin, salt and black peppers. (I cut the chicken into smaller bite size pieces so I would get more chicken with each bite.)Stir in the broth, tomatoes, sauce, and tomato paste. Cook an additional 6-8 minutes or until warm.Serve with fat-free sour cream (to tame some of the heat), tortilla chips (to add some crunch), and/or cilantro, or just eat it as it is.
