Trim any excess fat from the steaks, and cut them against the grain into 2cm strips.
Mix the remaining ingredients together to make a marinade.
Add the strips of steak to a large bowl and toss them in the marinade.
Cover and refrigerate overnight (or at least a few hours).
Thread the steak strips onto skewers.
Place the skewers on a very hot bbq and cook for just a few minutes each side (depending on how you like your steak cooked).
Serve with sticky rice, chilli dipping sauce and a salad of noodles, lettuce and spring onions.
