This recipe is a great way to add some freshness to your pork loin. The fennel and orange give the meat a fragrant and citrusy flavor that pairs well with roasted vegetables or a fresh salad. The pork is first rubbed with a mixture of fennel seeds, orange zest, and olive oil, then roasted in the oven until it's golden brown and juicy. Serve it with some roasted potatoes and a fresh salad for a complete meal.
