1. Soak bamboo skewers in water for at least 10-15 minutes. This will prevent them from burning on the BBQ.
2. Make the marinade by combining the spices, garlic, lemon and VEGEMITE.
3. Mix the marinade with the beef and allow to sit for 15-20 mins.
4. Thread the beef on to the bamboo skewers evenly.
5. Place the skewers on to a hot BBQ or grill plate and cook for 2-3 minutes each side or until well caramelised.
6. Serve with yoghurt and grilled red onion petals.
