Preparation Steps

• In a large bowl, whisk together peanut oil, soy sauce, garlic, ginger, ground cumin, smoked paprika, cayenne pepper, lemon juice, and brown sugar.
• Add the beef cubes to the marinade, tossing to coat evenly. Cover and refrigerate for at least 2 hours or overnight for best flavor.
• Preheat grill to medium-high heat and soak wooden skewers in water to prevent burning.
• Thread marinated beef, red onion chunks, and red bell pepper chunks alternately onto the skewers.
• Grill the kabobs for 8-10 minutes, turning occasionally, until beef is cooked to desired doneness and vegetables are tender.
• Remove from grill and let rest for 5 minutes before serving.
