In a large skillet, heat the butter and extra virgin olive oil over high heat. Salt and pepper both sides of each scallop. When the pan is hot (smoke will rise from the pan), add the garlic and stir well. Then place the scallops on the pan. Sear on each side for 1 ½ minutes.
In a medium bowl, combine all of the corn tomato relish ingredients and stir to combine.
To serve: spoon the relish onto 4 plates and place the scallops on top immediately after cooking.
