• 18 pickling onions, skins on
       
• 12 rashers streaky bacon
       
• 1 kg rump, cut into 2 ½ cm cubes
       
• 12 wooden skewers, soaked in water
       
• 18 button mushrooms, halved
       
• 1 red pepper, seeded and cut into squares
       
• 1 packet Royco® Spare Rib Marinade

• Boil pickling onions for 4-5 minutes, refresh in cold water, peel and cut in half.       
• Cut the bacon rashers in half, then roll each piece up.       
• Thread rump cubes onto the skewers, alternating with the pickling onions, bacon, mushrooms and red pepper squares.
• Prepare Royco® Spare Rib Marinade according to packet instructions. Marinate kebabs for 20 minutes.       
• To Cook       
• Braai kebabs over moderate coals, basting frequently, for about 10 minutes.      
• Grill kebabs in the oven for about 15 minutes, turning and basting frequently.     
• Serve immediately

Sirloin or fillet steak can be used for this recipe, but rump is the tastiest. The kebabs can be made a day ahead (as far as step 4) but only marinate 20 minutes before cooking.
