You can freeze this after cooking with no problem! I love to freeze my extra meat for my lunches or to make a busy weeknight meal go easier. Slice up the roast and wrap portioned amounts in Press-n-Seal.  Place wrapped up meat into a freezer-safe gallon Ziploc bag. If you don’t use a freezer-safe version, it won’t keep properly. Don’t skip this step. I also like to do it this way as I can open up the Ziploc bag and grab a portion-controlled, pre-wrapped Press n Seal package of meat to defrost while the rest can remain in the freezer-safe bag.
