I got this from Publix. I use pork chops instead of tenderloin. It's very quick and easy but i only get about two chops out of this mix. So, I double it or triple it depending on how many chops i make.
1) Crush garlic, using garlic press, into medium bowl. Use knife to remove garlic from bottom of press. Stir in brown sugar and steak seasoning until well blended.
2) Preheat large saute pan on medium heat 2-3 minutes. Cut pork diagonally into about eight 1-inch-thick slices. Place pork slices in bowl and press into mixture. Turn and press again to lightly season both sides (wash hands).
3) Place 1 tablespoon of the butter in pan; swirl to coat. Add pork (wash hands); cook 5-6 minutes on each side or until well browned and internal temperature reaches 160 degrees (for medium). Use a meat thermometer to accurately ensure doneness.
4) Remove pork from pan. Stir in wine and remaining 1 tablespoon butter; simmer one minute, stirring continually. Serve wine sauce with pork.
