How to Make It
Whisk together the olive oil, garlic, rosemary, parsley, red pepper, salt, and pepper. Place pork tenderloins in 13- x 9-inch baking dish, and coat evenly with olive oil mixture. Cover and chill 8 to 12 hours.
Preheat grill to medium (about 400°F). Grill tenderloins, covered with grill lid, until a meat thermometer inserted into thickest portion registers 140°F, 6 to 8 minutes on each side. Let stand 10 minutes. Cut into 1/2-inch slices, and serve immediately.
Total cook time includes 8 hours chilling.
