In large pan on medium high heat brown ground beef and sausage. Drain grease from pan. Turn heat down to low and add cubed Velveeta into pan with browned beef and sausage. Melt slowly, stirring frequently. When cheese is melted, add tomato sauce, Worcester sauce, garlic powder, and onion powder. Heat through for a few minutes. Serve warm on hamburger buns.
*This would also make a really good appetizer for parties. Place sausage and ground beef mixture on little Hawaiian rolls for smaller party portions.
