1) Preheat griddle.
2) Combine tomato ketchup and hoisin sauce in a bowl. Reserve some of the sauce in a small bowl and set aside.
3) Cut beef steak into 2.5cm pieces. Thread beef pieces evenly onto 4 (25 to 30-cm) metal skewers. Season kabobs evenly with pepper.
4) Place kabobs on rack in griddle pan so surface of beef is 7.5 to 10cm from heat. Brush beef generously with some of reserved sauce mixture. Cook 7 to 9 minutes for medium-rare to medium doneness, turning once and brushing with remaining sauce mixture.
5) Season beef with salt, if desired. Serve kabobs topped with pineapple salsa.Cook's tip: 2 beef shoulder top blade (flat iron) steaks (226g each) may be substituted for top sirloin steak. Cooking time remains the same.
Cook's tip: regular cucumber may be substituted.
For easier preparation, use peeled, cored and sliced fresh pineapple available in the supermarket produce section.
