Chop onion, garlic, and carrots into small pieces.
Brown ground beef in large skillet over medium-high. Add onions, carrots, and garlic and continue to cook 6-8 minutes until tender.
Add the rest of the ingredients and simmer 20-30 minutes or until thick (adjust chili powder and brown sugar to taste).
Meanwhile, slice corn tortillas into 8 wedges each. Arrange in a single layer on a cookie sheet; spray with cooking spray and sprinkle with salt to taste. Bake at 400°F for just a few minutes until chips begin to get brown and crispy.
Serve chili with chips and orange wedges on the side.
