Pineapple Pork Tenderloin is a healthy and flavorful dish that is perfect for a weeknight dinner or a special occasion. The tender and juicy pork tenderloin is marinated in a mixture of pineapple juice, soy sauce, garlic, and brown sugar, which adds a sweet and tangy flavor to the meat. To make this recipe, start by marinating the pork tenderloin in the pineapple juice mixture for at least 1 hour, or overnight for maximum flavor. Then, preheat your oven to 425°F and roast the pork tenderloin for about 20-25 minutes, or until it reaches an internal temperature of 145°F. Let the pork rest for a few minutes before slicing it. Serve the Pineapple Pork Tenderloin with a side of roasted vegetables or a fresh salad for a complete and healthy meal.
