In my defense, that pic was more to show quantity than quality. It looks better on the plate.
I use FoodSaver brand and I basically just charcoal grill the meat, let it rest 5 minutes so the juices reabsorb and then I seal it while still hot. Once it cools a little I throw it in the fridge and it will last at least 10 days with no degradation in quality. I usually eat through that much quicker though - I only found out it was still good after 10 days when I forgot about a chicken breast while on vacation. Tasted yummy when I got home.
EDIT: hmmm looks like tnation decided to rotate my picture for me...lol looks tastier if you tilt your head
