1. Preheat your oven to 400°F (200°C).

2. Rub the pork tenderloin with Rub it Up Cajun pineapple Blend, olive oil, salt, and pepper.

3. In a small bowl, mix the pineapple juice and brown sugar until the sugar dissolves.

4. Heat an oven-safe skillet over medium-high heat. Sear the pork tenderloin on all sides until browned, about 3-4 minutes per side.

5. Pour the pineapple juice and brown sugar mixture over the pork. Transfer the skillet to the oven and roast for 20-25 minutes, or until the pork reaches an internal temperature of 145°F (63°C).

6. Let the pork rest for 5 minutes before slicing. Garnish with fresh herbs like parsley or thyme.

7. Serving suggestion: Serve with mashed potatoes or roasted vegetables for a comforting meal.
