Brown ground bison meat in a large Dutch oven or a stockpot over medium-high heat for about 15 min. Break it up with a wooden spoon as you stir. When the water evaporates, add 2 tbsp of avocado oil and continue to brown.
Transfer the browned meat into a separate bowl and set aside.
Next add the remaining avocado oil and diced onions to the same pot and sauté until onions are lightly golden. Then add the minced garlic and sauté for a few minutes.
Stir in the browned bison meat, the chili powder and cumin, mix well, cover and cook for additional 10 min on low.
Add the diced tomatoes, water and drained beans, give it a good stir and continue to cook over medium heat, uncovered, until the water evaporates.
Transfer into individual bowls, add desired garnish and serve!
Notes
You may cook this chili in a slow cooker on high setting in 2 hours, but I recommend browning the onions and meat first.
This chili pairs well with the Buttermilk Skillet Cornbread. If you use jalapeños in the cornbread, you may want to skip them as garnish on the chili.
This chili is thick, but if you like yours thinner, add more water.
For a vegetarian variation, omit the meat; the beans will serve as your source of protein.
