1. Grind sesame seeds in a grinder or mortar and pestle then combine with garlic, soy, honey, sesame oil, fish sauce, ginger and the juice and zest of 1 lime.
2. Slice the beef in long strips, 1 cm thick and add to the marinade. Stir a little to cover in sauce and leave to marinate for 30 minutes.
3. Heat the barbecue or grill pan. Thread the beef on to bamboo skewers and cook 3-4 minutes each side.
4. Chop the other two limes in half and grill at the same time.
5. Serve beef skewers with grilled limes for squeezing. This is good with steamed rice and kimchi. Or with lettuce leaves to make wraps.
