Gather all supplies
Dice onion into small/medium pieces
Drain any fluid from your kidney beans as well as diced tomatoes.
Start cooking your ground beef
Cook until light brown, it's ok to have a little pink as it will finish cooking in the crockpot.
Add your browned hamburger, kidney beans, tomatoes and onions into crockpot.
Add minced garlic (I used about a tbsp, you can use more or less depending on how much you like garlic)
Add in contents of your chili mix packet
I like to add extra chili powder for more flavor (optional)
Add a few dashes of crushed red pepper flakes and some ground black pepper and mix all ingredients together.
Set your crockpot on low to cook for 6-8 hours.
Fast forward 8 hours and this is what you have!
Add a little shredded cheddar cheese if you like!
