1In a large pot or Dutch oven, heat the oil over medium high heat. Add the bacon and cook until the fat renders, about 2 minutes. Add the beef and brown that also, stirring occasionally, about 8 to 10 minutes.
2Add the onions, cooking until softened, about 5 minutes. Stir in garlic, a little salt, lots of pepper, tomato sauce, Worcestershire sauce, brown sugar, hot sauce, and beef stock. Heat to boiling, then lower heat and cook until thickened, 6 to 7 minutes.
3Divide chili into individual serving bowls, top with a dollop of sour cream, and garnish with parsley.
