So you have that HUGE boneless pork loin from Costco.  Just cut it into usable pieces (1/4 lb per person.) and freeze in individual bags.  Come dinner time (or unexpected guests) just defrost (in the microwave if necessary) and brush on the sauce (adjust for the size of you meat) and cook.  You can even cook it in the microwave.  The sauce is also good on chicken.

Ingredients:

• 1 12 oz frozen orange juice concentrate – don’t reconstitute
• 1/4 c soy sauce
• 10# pork roast

Directions:

1. Heat oven to 350°.
2. Pat pork dry with paper towel.
3. In small bowl, combine soy sauce and orange juice concentrate.
4. Apply to all surfaces of the pork roast.
5. Place roast in a shallow pan and roast in a 350°. oven for 1 hour (20 minutes per pound), until internal temperature on a meat thermometer reads 145°.  Do not overcook.  Pork today is very lean – no fat means dry meat.
6. Remove roast from oven.
7. Let rest about 10 minutes before slicing to serve.

Serves:  40  (plan on 1/4 to 1/3 pound per person.)
