Heat a large stockpot or Dutch oven over medium high heat. Crumble beef into the pot. Add onion and garlic; cook and stir until beef is brown; drain.
Stir in chili powder, oregano, cumin, and hot sauce until well combined. Pour in tomatoes and vinegar; bring to a boil. Reduce heat to low; simmer for at least 1 hour, stirring occasionally to prevent burning.
