In a blender, puree the cilantro, 1/2 cup pineapple juice from the canned pineapple rings, honey, lime juice, 1/4 tsp salt, and 1/4 tsp pepper
Reserve 1/4 cup of the cilantro sauce and pour the rest into a medium bowl with the pork chops and sprinkle with the remaining 1/4 tsp salt
Turn the pork to coat and let sit for 5 minutes
Meanwhile, brush the pineapple rings and onion rings with olive oil
Add the pork, pineapple, and onion rings to the grill and cook for about 3-5 minutes per side, or until the pork is cooked through and pineapple and onions are soft
Serve the pork with the grilled pineapple and onions drizzled with the remaining cilantro sauce and lime wedges
