Juicy pork tenderloin cut into medallions and sauteed in a rich port wine sauce is a dinner that can be made quickly on a weekday or used for a special weekend treat. The skillet potatoes are crisp and golden and take only minutes to make.

“Ketchup in your sauce!” was my surprised comment when I saw famed television chef Jacques Pepin prepare this pork recipe. “Sure, ketchup or a thick tomato sauce has been used in French cooking for many years. It gives just the right amount of sweet and savory flavor and texture,” he said with a smile. I have adapted his recipe for this quick dinner.

Helpful hints

• The quickest way to wash watercress is to place it head first into a bowl of water. Leave for a minute, then lift out and shake dry.

• A washed ready-to-eat salad can be used instead of the watercress.

• Sherry can be used instead of port.

Pork in Port Wine

¾ pound pork tenderloin

1 teaspoon olive oil

Salt and freshly ground black pepper

½ cup port wine

½ cup fat-free, low-salt chicken broth

2 tablespoons ketchup

½ teaspoon dried thyme

1 small bunch watercress

2 tablespoons reduced-fat vinaigrette dressing

Remove visible fat from pork and cut crosswise into 1-inch slices. Heat olive oil in a nonstick skillet over medium-high heat. Brown pork 3 minutes per side. Salt and pepper cooked sides. A meat thermometer should read 145 degrees. Remove to two dinner plates. Add the port to the skillet and bring to a boil, scraping up the brown bits as wine boils for about 1 minute. Add the chicken broth and ketchup stirring to combine; cook about 2 minutes. Sprinkle with thyme. Spoon sauce over pork. Mix the watercress and salad dressing together and add to the plates. Makes 2 servings.

Skillet Potatoes

¾ pound yellow potatoes, peeled and cut into ¼-inch slices

2 teaspoons olive oil

½ cup water

Salt and freshly ground black pepper

Arrange potato slices in a single layer in a large nonstick skillet or 2 small skillets. Mix the oil and water together and add to skillet. Bring to a boil and cover with a lid. Simmer 5 minutes. Most of the water will be evaporated and potatoes soft. Uncover and cook, turning slices until they are browned on both sides, about 1 minute. Sprinkle with salt and pepper to taste. Makes 2 servings.
