Steps
1. In a bowl, combine the beef cubes with BBQ sauce, olive oil, garlic powder, onion powder, salt, and pepper. Mix well to coat the beef.
2. Allow the beef to marinate for at least 30 minutes.
3. Preheat the grill to medium-high heat.
4. Thread the marinated beef, bell pepper, and onion onto the skewers, alternating between each ingredient.
5. Grill the skewers for about 10-12 minutes, turning occasionally, until the beef is cooked to your desired doneness.
6. Serve hot with extra BBQ sauce on the side.
