If you enjoy authentic Mexican food, you're probably already familiar with the shepherd style tacos that inspired this recipe. Pan searing not only keeps the cooking method lean, but it also intensifies the inherent sweetness of the pineapple. The recipe came from flat belly diet meal. I never once would dream of cutting up a pork tenderloin in cubes, but the recipe called for it and I am glad I tried this. This is one of the best recipe that I have ever eaten. I did use all of the pork tenderloin and cooked it in batches because my husband loves to eat.
