Grilled Chimichurri Pork Tenderloin

Heat gas or charcoal grill. Soak twine in water to prevent burning. In medium bowl, mix olive oil, lime juice, parsley, garlic, 1/4 teaspoon of the salt, the oregano and pepper flakes.

Make 1-inch cut down length of tenderloin; do not cut all the way through. Press sides of tenderloin down so it lies flat. Cover with plastic wrap; pound with flat side of meat mallet to 1/2 inch thick. Spread parsley mixture over tenderloin to within 1/2 inch of edges. Tightly roll up tenderloin lengthwise. Tie tightly with twine.

Melt 2 tablespoons of the butter. Brush tenderloin with butter, then rub in chili powder, smoked paprika and 1/2 teaspoon of the salt. Place on grill over medium heat. Cover grill; cook 17 to 22 minutes, turning frequently, until thermometer inserted in center of tenderloin reads 145°F. Transfer to cutting board; cover with foil and let stand 5 minutes. Cut and discard strings. Cut tenderloin into slices with serrated knife.

Meanwhile, melt remaining 4 tablespoons butter. Coat corn with butter, and sprinkle with remaining 1/2 teaspoon salt. Grill 4 to 6 minutes, turning frequently, until golden brown on several sides. Top with queso fresco and cilantro. Serve tenderloin with corn and lime wedges.
