Chop onion and set aside.
In a large bowl, whisk egg. Add onion, bread crumbs, dry soup mix and all of the sauces. Mix well.
Add ground beef and salt and pepper. Mix well. I usually get in with my hands to mix well.
Separate mixture into firm balls approximately 5 ounces each. Press into burgers.
BBQ until cooked well, approximately 4 to 6 minutes per side.
