Start with the marinade by combining all the ingredients in a medium bowl and whisk well.
Add the pork cubes in the bowl of the marinade and refrigerate for 1 hour or even better overnight.
Remove from the refrigerator 1 hour prior to cooking and put on skewers while adding between the pork cubes a piece of pepper and onion.
Set a large grill pan over high heat and let it heat up for 2’. Add the pork skewers turning frequently for about 12’.
Serve with the bulgur and optionally with some yoghurt.
