Favorite Savory Pork Tenderloin

Favorite Savory Pork Tenderloin
Adapted by Elephant and Chick from Favorites

This is from the Favorites Cookbook, which is fittingly a favorite at our house.  I don't think it's originally supposed to be a crock pot meal, but we do it in the crock pot every time and love how it turns out.  Serve with your favorite mashed potatoes and veggie.

1 pork tenderloin

Marinade:
1 1/4 cups vegetable oil
3/4 cup soy sauce
1/4 cup Worcestershire sauce
2 T. dry mustard
1 T. pepper
1/2 cup red wine vinegar
1 1/2 T. parsley
1/3 cup lemon juice
2 cloves garlic, minced

Blend the above marinade ingredients in blender.  Pour over tenderloin in the crock pot and cook on low for 4-6 hours.
