In a large skillet over moderate heat, cook onion, bell pepper and garlic in oil for 5 minutes or until vegetables are softened. Transfer mixture to a small bowl.
Cook ground beef in the same skillet over medium-high heat for 5 minutes or until no longer pink, breaking up lumps with a spoon as meat cooks. Stir in onion mixture, chili sauce, TABASCO® Caribbean-Style Steak Sauce, and vinegar; cover and simmer 10 minutes, stirring once. Serve on toasted rolls.
