Have not made this yet, but it looks very tasty. After the rub, I might also marinade the pork in the soy/oil mixture for an hour or so prior to grilling. Rather than using 16 wooden skewers, I think I will use 8 metal skewers for ease of preparation. So more tomatoes on each skewer, etc...So may need more grilling time as well.
