Soak the sea scallops in the butter for 20 minutes, turning occasionally to coat. Meanwhile, cook the quinoa according to package directions.
In a medium bowl, combine the tomato, red or green bell pepper, cucumber, corn, garlic, lime juice, olive oil, red pepper flakes and salt & pepper.
Remove the scallops from the butter and sprinkle them with salt and pepper. Cook scallops on a grill over medium heat for 3-4 minutes per side. Serve quinoa, vegetables and scallops together.
