4 teaspoons packed dark brown sugar 2⅛ teaspoons kosher salt 1⅛ teaspoons pepper 2 (12- to 16-ounce) pork tenderloins, trimmed1 cup baby spinach 2 tablespoons olive oil

  2. for the tenderloin

  3. Combine sugar, 2 teaspoons salt, and 1 teaspoon pepper in bowl. Cut each tenderloin in half horizontally, stopping ½ inch away from edge so halves remain attached. Open up tenderloins, cover with plastic wrap, and pound to ¼-inch thickness. Trim any ragged edges to create rough rectangle about 10 inches by 6 inches. Sprinkle interior of each tenderloin with remaining ⅛ teaspoon salt and remaining ⅛ teaspoon pepper.
  4. With long side of pork facing you, spread half of stuffing mixture over bottom half of one tenderloin followed by ½ cup spinach. Roll away from you into tight cylinder, taking care not to squeeze stuffing out ends. Position tenderloin seam side down, evenly space 5 pieces twine underneath, and tie. Repeat with remaining tenderloin, stuffing, and spinach.

Why This Recipe Works

Butterflying and pounding the pork in our grilled pork tenderloin recipe created a larger surface area for the filling, which we rolled up inside the pork tenderloin before trussing to prevent leakage. A traditional bread stuffing oozed out of the pork as it cooked, so we opted to fill our grilled stuffed pork tenderloin with a robustly flavored paste. We grilled the tenderloin over a modified two-level fire and rubbed some brown sugar onto its exterior. This gave our grilled stuffed pork tenderloin a moist interior and a perfectly browned crust.
