Heat the olive oil in a large skillet over medium-high heat. Add the onions and garlic sauté until they soften, but don’t brown, for about five minutes.
Add the peppers and celery and sauté until lightly browned and tender, about 5 minutes.
Set your slow cooker to low. Add the beans, vegetables, diced tomatoes, spices, vinegar, and hot sauce. Stir to combine and cover. Cook on low heat for 6 to 8 hours.
Serve with shredded cheese and sour cream (optional).
Chili will keep in an airtight container in the fridge for five days or in the freezer for up to four months.
Notes
Recipe will comfortably fill an 8 quart slow cooker and fill a 6 quart slow cooker almost to the top.
