Place a large Dutch oven over medium heat and add avocado oil to coat the bottom of the pan.
Once the oil is hot, add diced onions and sauté until translucent and beginning to brown. Add minced garlic and sauté 1-2 minutes more.
Whisk chili paste and broth (or stock) into the onions and garlic, whisking until the chili paste is evenly distributed throughout the broth. Bring to a simmer.
Add cooked chicken, tomatoes, and beans. Continue to simmer for 15 minutes.
Taste chili and add salt, if needed. Simmer for 5 minutes more.
Serve chili with toppings, or refrigerate and reheat to serve the next day. Homesteading Hack: Flavors will continue to develop over 24 hours, so the chili often tastes better the next day.
