Put the pork tenderloin in the bottom of a slow cooker.
Pour water, wine, and Worcestershire sauce into the slow cooker.
Top the pork with minced garlic.
In a small bowl, stir together remaining ingredients. Sprinkle mixture over pork.
Cover slow cooker and cook on LOW for 4-5 hours (if possible, flip pork over halfway through cooking) or HIGH for 2-3 hours.
Serve pork with the gravy in the slow cooker.
*Use 1 to 1.25 pounds pork tenderloin*To double the recipe, double all the ingredients except the wine, water, dried minced onion and onion powder. Use only 1 cup water, 1 cup wine, 2 tablespoons onion flakes, 1/4 teaspoon onion powder.*Be sure to use a wine you enjoy drinking!*You can use less wine if you want or skip the wine altogether. Unsalted chicken or beef broth is ok, but you will likely need to add more spices. Make sure the liquid totals 1 1/2 cups.*To make a slightly thicker gravy, whisk together 1 tablespoon cornstarch and 1/4 cup cold water. Stir the mixture into the slow cooker and cover. Let sit for 10-15 minutes. The gravy will be a little thicker.
