Soak at least 8 bamboo skewers in cold water for 30 mins.
Slice the beef into long thin strips, 2.5cm wide and 5mm thick.
Mix the sugar, mirin (or sherry), soy, sunflower oil, mustard and lime juice together in a shallow dish. Place the sliced beef in, cover and leave to marinate for 10 mins.
Heat a ridged griddle pan (or grill). Don’t add oil. Place a strip of tin foil over one half of the pan to prevent the skewers burning.
For the salad, combine the sliced veg sticks in a bowl. Mix the sesame oil, lime juice and sesame seeds and pour over the veg and toss.
Thread the beef onto the skewers in a zigzag fashion. Place on the pan with the sticks on the foil and cook for 1-2 mins each side, turning with tongs. Lift them off and brush with warm honey before serving with the salad.
