Preheat large, nonstick saute pan on medium-high 2-3 minutes. Place beef in pan (wash hands); brown 5-7 minutes, stirring to crumble meat, or until no pink remains. Stir in taco seasoning; remove meat from pan.
Combine remaining ingredients in slow cooker; stir in meat. Cover and cook on HIGH 3-4 hours or LOW 6-8 hours. Serve.
Short on time? Simply assemble the chili in a large stockpot and simmer for 18-20 minutes on your stovetop.
