Make the beef tenderloin marinade by combining soy sauce, vinegar, ginger, garlic, sesame oil, olive oil, sugar, salt, and ground black pepper in a large bowl. Mix well.

Add the cubed beef tenderloin on the bowl with the beef tenderloin marinade. Gently toss to coat the beef. Let it stay for 1 hour.

Using a metal or bamboo skewer, assemble the beef kebob by skewering the vegetables and marinated beef tenderloin.

Heat-up the grill and start grilling the beef kebobs for 3 minutes per side. This will give you a medium beef that is juicy and tender in the inside. Add more time if you want your beef well done, but it will be less tender.

Transfer to a serving plate. Serve with Saffron rice.
