Preheat the Blackstone griddle to medium-high heat.
In a bowl, mix the olive oil, minced garlic, paprika, oregano, salt, and pepper.
Thread the shrimp onto the soaked wooden skewers.
Brush the shrimp skewers with the prepared olive oil mixture, coating them evenly.
Place the skewers on the preheated griddle and cook for 2-3 minutes per side, or until the shrimp are pink and opaque.
While grilling the shrimp, warm up the cooked rice.
Serve the grilled shrimp skewers over the rice, garnished with freshly chopped parsley.
