Preheat oven to 375 degrees.
In large bowl whisk together eggs, au jus, pepper, dry mustard, and onion powder.
Mix in beef and panko crumbs.
Don't over mix, just until combined.
Divide mixture in half and place onto a parchment lined baking sheet.
Form each half into a foot shape like in the pictures above.
Cut a thick slice of the onion and using one ring, cut toenail shapes for each toe.
Slice two small onion rings and place onto the top of the ankle part (creating a stump).
Spoon on a little ketchup over each onion ring and spread a little so some of it will drip down the sides.
Bake for 40-50 minutes or until center is cooked through.
Cool for 5 minutes before serving.
My family likes to eat it with ketchup or stewed tomatoes. I prefer mine with brown gravy.
