Grated red onion
This is pretty simple. Mix ingredients in a bowl. Season as if you are preparing hamburgers, and then add a couple tablespoons of parsley, red onion, and maybe a tablespoon of chopped garlic.
Lightly shape meat around a skewer until it forms what looks like a hot dog. Don't press meat too hard or it will get tough. Now just grill over high heat until done to your likeness.
