Mix the Zaika™ Smokey BBQ Marinade, water and oil in a bowl to make a paste. Marinate the beef for at least 4 hours (recommended).
Slowly grill the beef over a barbeque until cooked through.
Meanwhile, Pre-heat the oven at 300oC. Clean the potatoes, poke with folks, and rub the butter / olive oil, salt and pepper and cover with silver foil. Bake until cooked through.
Pull and shred the meat. Push open the potato, add cheddar cheese and the meat on top and bake for 5 minutes until the cheese has melted. Serve hot.
