Pork that's marinated overnight in a combination of fresh lemon juice, fresh orange juice, and spices is flavorful and succulent with a little bit of a kick. I use boneless center cut extra-thick pork chops for this dish. If you don't have time to do this the night before, try to marinate for at least 3 hours before grilling, but if you only have 30 minutes to marinate, go for it; you'll still get a little tangy fruit flavor on your pork.
Threading the skewers with chunks of fresh lemon and orange, with their peels still on, gives you color that complements the pork -- and you can squeeze the grilled fruit over the meat for an extra hit of flavor. Soak the wooden skewers in water for at least 60 minutes before threading on the meat. And if the weather isn't cooperating, you can make these skewers under your broiler too.
