Remove attached abductor muscle from scallops and gently rinse. Thoroughly dry each scallop with a paper towel. Preheat a large cast iron skillet to medium high with 2 tbsp olive oil. Sear scallops until deep golden brown approximately 1 1/2 -2 minutes on each side depending on the size of the scallops.

Drizzle each scallop with cilantro sauce and garnish with lime zest.  Serve immediately.  Enjoy!
