I don't do much with roasts but the feed a family for $99 a week in Womans Day for August had this and I wanted to try it.
1 1/2 tsp each chili powder and paprika
1/2 tsp garlic powder
1/2 tsp pepper
3 lb boneless center cut pork loin(mom gave me a roast so that's what I used)
Heat oven to 375. Mix all ingredients and rub mixture over pork. Place in small roasting pan.
Roast 50 minutes or until instant thermometer registers 150F. Remove from oven and let rest 15 minutes before cutting to serve.
