I bought 2 packs of those the last time they had a sale like that. I cut them up into 3 roasts per pack, and vacuum paced for the freezer. They have been great here and there for an easy weekend dinner or such.
I generally followed this recipe. Edit, my cook was half a loin, just over 3lbs. I did not half the marinade or glaze. https://www.epicurious.com/recipes/food/views/glazed-pork-loin-with-cilantro-and-garlic-352949
