Serving Suggestions
Transform this dish into a complete meal by pairing it with complementary sides. Serve over creamy mashed potatoes or fluffy rice to soak up extra sauce. Consider offering roasted vegetables or a fresh rocket salad alongside. For entertaining, slice and arrange on a platter with extra sauce for passing. Present with lemon wedges and fresh herbs for garnish.
Creative Variations
Elevate this versatile dish by experimenting with different herb combinations. Try cilantro instead of oregano, or add mint for brightness. Consider incorporating lime juice instead of vinegar, or create a spicier version with extra chili flakes. Make it your own with additions like shallots or cumin.
Storage Solutions
Maintain the perfect flavor by storing components separately. Keep sliced pork in airtight containers for 3-4 days, with sauce stored separately for 2-3 days. For reheating, warm pork gently with a splash of broth to maintain moisture. Allow sauce to come to room temperature before serving. Slice only what you plan to serve immediately.

While simple to prepare, attention to meat temperature and fresh ingredients creates spectacular results that elevate humble pork tenderloin.
