Step 1

Combine pineapple juice, soy sauce and olive oil in a freezer zip-top bag. Place tenderloins in bag, place bag in a bowl (in case of a leak) and marinate 1 to 2 hours.

Step 2

When ready to cook, preheat oven to 400 degrees F, remove tenderloins from the bag and sprinkle with salt, pepper, and crushed rosemary.

Step 3

Bake 30 minutes or until a meat thermometer inserted in the thickest part registers 160 degrees. Allow to rest 10 minutes before slicing.
