Citrus and Soy-Marinated Grilled Pork Tenderloin
2-3 pounds pork tenderloin
3/4 cup olive oil
1/3 cup soy sauce
2 tablespoons Worcestershire sauce
1 tablespoon dry mustard
1 teaspoon salt
1 teaspoon black pepper
2 tablespoons red wine vinegar
1 teaspoon dried parsley flakes
2 cloves garlic, finely minced
2 tablespoons freshly squeezed lemon juice (from about 1 lemon)
Combine all the ingredients except the pork and mix well. Pour the marinade into a ziploc bag or baking dish and add the pork tenderloin, making sure the marinade completely covers the pork. Marinade for 8-10 hours.
Preheat an outdoor grill (charcoal or gas). Grill the pork tenderloin about 3-4 minutes on each of its four sides (the exact time will depend on the temperature of your grill) or the internal temperature is about 150 to 155 degrees. Remove from the grill, tent with foil, and allow to rest 10 minutes before slicing and serving.
