  3. Step 3: Sprinkle 1 tablespoon chopped fresh rosemary over the potatoes and carrots, drizzle with 1 tablespoon olive oil, and toss gently to coat.
  4. Step 4: Roast in the oven for 25-30 minutes until the pork reaches an internal temperature of 145°F and the vegetables are tender and golden.
  5. Step 5: Remove the pork and vegetables from the oven, let the pork rest for 5 minutes before slicing, and serve with the roasted vegetables.
