In a large mixing bowl, combine the ground beef, pork, and veal with a wooden spoon or with clean hands. Be sure to wash up afterward.
In a medium mixing bowl, combine the eggs, heavy cream, ketchup, Baby Bam, Dijon mustard, and Worcestershire sauce, and whisk to combine. Add the egg mixture to the meat mixture along with the cooled vegetables and bread crumbs. Mix with your hands or a wooden spoon until thoroughly combined.
Transfer the mixture to a 9 by 5 by 3-inch loaf pan. Using your fingers or the back of the wooden spoon, smooth the top into a rounded loaf shape. Wash hands again.
