My famous roast pork. Very easy to make and is terrific.
Start with a pork tenderloin (recently they have been offered are a really good price). Make a mixture of
1/4 cup Worcestershire sauce,
1 tbsp dry mustard (you could also use Dijon),
1 tbsp garlic powder and pepper.

Actually the proportions can be altered depending on your taste.

Brush the roast with the mixture, add a little water to the bottom of the pan and put it into the oven at 325 for 2 hours.
Baste periodically and add more water to the bottom of the pan when it dries out.

Really good for sandwiches the next day too.
