Preheat grill to medium-high heat.
In a large bowl, combine ground beef, seasoning packet, ketchup, bread crumbs, and egg. Mix until just combined; do not overmix. Shape into hot dog forms. Grill for approximately 8 to 10 minutes. Serve on hot dog buns with more ketchup, relish, and chopped onions.
