Add the parsley, oregano, red pepper flakes, garlic, salt, and pepper into a food processor. Blend until all the ingredients are very finely chopped and well blended. Pour into a bowl.
To the bowl, pour in the white wine vinegar and olive oil. Mix with a spoon, then store in the fridge for at least an hour.
For the Lamb Chops
Pat dry the lamb chops and season with salt and pepper.
Turn the grill on to medium high heat, spraying with nonstick spray. Add the lamb chops to the grill and cook for 3-4 minutes per side for medium rare, or until the internal temperature reaches 135º-140º.
Remove the lamb chops from the grill and spoon the chimichurri on top, then serve.
Notes
Use a Meat Thermometer - I cannot recommend this enough, once I started using a meat thermometer, my grilled meats consistently taste exactly as they should and cooked to a perfect temperature. Lamb chops, while pretty forgiving, are traditionally cooked to a medium rare.Let the Sauce Marinade - Make the chimichurri ahead of time and let it sit for at least an hour or two so that the ingredients marinade and meld together.
