Get the oven hot, about 350 degrees.
Apply nonstick cooking spray to a loaf pan.
Put the ground beef, shredded bread, onion, egg whites, salt, and pepper in a big bowl and mix well. Keep aside.
The Worcestershire sauce, mustard, and ketchup should be whisked together in a small bowl.
Over the ground beef mixture, pour the sauce components that have been blended. Mix the meat and sauce together using your hands.
Roll out the bread. After you have the loaf pan ready, transfer the beef mixture into it. Cook in a preheated oven.
Half an hour in the oven at 350 degrees should do the trick. Check to see that the meatloaf is done cooking.
Remove from oven, place on a cooling rack, and let cool for 10 minutes.
Make five equal pieces. Arrange on a platter and get ready to devour.
