1. Cook ground beef and next 5 ingredients in a Dutch oven over medium heat 10 minutes or until meat crumbles and is no longer pink. Stir in diced tomatoes with green chiles and next 9 ingredients, and bring to a boil. Cover, reduce heat to low, and simmer 1 hour and 45 minutes, stirring every 20 minutes. Add kidney beans and black beans; cover and cook 15 minutes.
2. Cut corn chip bags open at one long side. Spoon 1/2 cup chili on chips in each bag. Garnish, if desired.
Note: Chili may be frozen in a zip-top plastic freezer bag up to 3 months. For testing purposes only, we used Fritos Brand Original Corn Chips.
