Heat oven to 375 °F. Add meat to a large bowl along with the egg, salt, pepper, mustard, Worcestershire sauce, crackers, and olives.

Using your hands, mix the ingredients together until well mixed.

With wet hands, pat mixture into a 9×5-inch loaf shape on a foil lined and non-stick spray coated baking sheet.

Bake until crisp on top and cooked through, about 1 hour.

Cool slightly and serve with ketchup.
