Slice the pork fillet into 2inch cubes.
Add all the ingredients for the marinade to a mixing bowl.
Add the chopped pork meat. Cover and place in the fridge to marinade for at least 3 hours.
Soak bamboo skewers for at least an hour before you start - this will help prevent them from burning under the grill.
To make the dipping sauce - add all the ingredients to a non-stick pan.
Bring up to a medium-heat for a minute until all ingredients are well combined. Transfer to a bowl to cool.
Thread the pork onto the skewers.
Arrange on a tray and grill for approx 4 minutes each side.
Keep some of the marinade liquid to baste about half-way. (Disregard the remaining marinade liquid.
Once cooked, serve the skewers with the peanut dipping sauce and slices of fresh lime.
