Preheat oven 350 degrees F.

Line 3 (9-by 5-inch) loaf pans with wax paper and set aside.

Make bread crumbs by placing the bread in the work bowl of a food processor and processing until finely ground. Transfer crumbs to a large bowl. Add all ingredients, except ketchup, to the bowl; mix until just combined. Divide and shape the meat mixture into loaves in the prepared pans. Spread a layer of ketchup over the top to cover the meat loaf. Bake for 1 hour and 30 minutes, or until completely cooked through. Remove from heat and let meatloaf cool for 15 minutes before slicing. Serve warm.
