Preheat your oven to 400°F.
Pat the pork loin dry and season generously with salt, pepper, and the mixed herbs. Mince or crush the garlic and rub it onto the pork for added flavor.
Heat a skillet over medium-high heat and sear the pork loin on all sides until a golden crust forms, about 2 minutes per side.
Transfer the pork to an oven-safe dish and place in the preheated oven. Roast for about 15-20 minutes or until the internal temperature reaches 145°F for medium-rare, adjusting cooking time based on your preferred doneness.
While the pork is roasting, peel and cube the sweet potato. Toss the cubes with a light drizzle of olive oil, salt, and pepper, and spread them on a baking sheet.
Cut the broccoli into florets, toss with a small amount of olive oil, salt, and pepper, and arrange them on another baking sheet.
Roast the sweet potatoes and broccoli in the oven for 15-20 minutes. For the broccoli, if needed, finish under the broiler for 2-3 minutes to achieve a crispy texture.
Once the pork has rested for 5 minutes, slice it thinly. Plate with a serving of roasted sweet potatoes and crispy broccoli, and enjoy your balanced, nutrient-rich meal.
