Either in a large pot over medium heat or in an InstantPot on saute, cook ground beef with garlic and onion till meat is browned.
Add all other ingredients and stir to combine.
Simmer on medium on the stove for 1 hour or in the InstantPot on "Beans/Chili" for 30 minutes. Or you can throw it all into a slow cooker and cook for 6-8 hours on low.
Top with chopped avocado and serve warm. If not on a Whole30 or Keto diet, it's delicious with crunched up plantain chips as well!
Freezes great, feel free to put the leftovers in individual or large glass container and freeze for up to 3 months.
