In a skillet, melt butter in olive oil. Add beef, garlic, onions, salt and pepper. Cook until meat loses red color, stirring occasionally.
Drain off any excess fat. Stir in water or broth, Worcestershire sauce, and ketchup. Simmer, stirring occasionally, for 15-20 minutes or until desired consistency.
Serve in toasted buns.
Any leftovers may be frozen for up to 6 months or refrigerated for 3-4 days.
