I have this recipe and I have another one..but..it calls for a crockpot and it takes all day to cook..not sure how soon you need it.
Seasoned Pork Loin Roast:
In the summertime..grill it if you want and in the winter time...roast it
2 teaspoons garlic salt
2 teaspoons garlic-pepper blend
2 teaspoons lemon-pepper seasoning
1 boneless rolled pork loin roast (about 5 lb.s)
BASTING SAUCE:
3 cups water
2 tablespoons lemon juice
1-1/2 teaspoons minced onion
1/2 teaspoon garlic salt
1/2 teaspoon garlic-pepper blend
1//2 teaspoon lemon-pepper seasoning
1/2 teaspoon red pepper flakes
1/2 teaspoon grated lemon peel
Combine the garlic salt, garlic-pepper and lemon-pepper; rub over roast. Place on a rack in a shallow roasting pan. Bake, uncovered, at 325 for 1-1/2 to 2 hours or until a meat thermometer reads 160.
Meanwhile, in a large saucepan, combine the basting sauce ingredients. Bring to a boil; reduce heat. Simmer, uncovered, for 10 minutes. Brush over roast occasionally while baking. Let the roast stand for10 minutes before slicing.
