Spinach and feta stuffed pork tenderloin is an elegant and delicious dinner option. A butterflied pork tenderloin is filled with a mixture of sautéed spinach, crumbled feta cheese, and garlic. The tenderloin is then rolled up and roasted until it is juicy and tender. The combination of flavors in this dish is fantastic. The spinach adds a pop of freshness, while the feta cheese adds a creamy and tangy element. Serve the stuffed pork tenderloin with roasted potatoes or a side of steamed vegetables for a complete meal.
