Full Portion serves 4-6. Half Portion serves 2-3. This recipe is an easy, melt in your mouth pork tenderloin in a buttery garlic sauce. The tenderloin comes rubbed with a garlic herb mixture, topped with tabs of butter and placed in foil, then sealed. Just pop it in the oven for 25-30 minutes. What could be easier! Great with Shallot Glazed Green Beans and Feta Herb Risotto.
