Heat a large pot over medium heat. Add the avocado oil, celery, onion, and bell pepper and cook for 7-8 minutes, stirring frequently, until the onions are translucent and turning golden brown. Transfer the cooked vegetables to a bowl.
Return the pot to the stove and increase the heat to medium-high. Add the ground beef. Crumble the beef and cook for 6-8 minutes or until browned. Drain off any excess fat if needed.
Add the minced garlic, spices (chili powder, cumin, paprika, onion powder, and salt), and tomato paste. Stir and cook for 3-4 minutes, until a deep red color and fragrant.
Return the vegetables to the pot. Add the beef broth, canned tomatoes, Worcestershire sauce, and hot sauce (if using). Bring the chili to a simmer and cook uncovered for 10-12 minutes until a deeper red color and the sauce has thickened.
Season the chili to taste with salt and pepper. Serve hot with your favorite sides.
