1. Preheat grill to 350° to 400° (medium-high). Sprinkle fillets with pepper and salt.
2. Grill, covered with grill lid, over 350° to 400° (medium-high) heat 4 to 6 minutes on each side or to desired degree of doneness. Let stand 5 minutes.
We cook our tenderloin fillets to medium-rare. If you like your meat cooked medium or well done, increase the grilling or pan-searing time per side. (Cook approximately 1 minute more on each side for medium, 2 minutes more on each side for medium-well, and 3 minutes more on each side for well done.)
