I have been living and cooking for one for the last 10 years, right now I am eating leftover ham from Easter cut off the bone and some ham went in freezer rest I make grilled ham and cheese, otherwise I put meat in freezer bags and cook as single servings
We've got some ham from Easter in the fridge, and since it was a 20 pounder, I cut it into 4 sections and we froze three at about 5 pounds each.
Additionally, last week Mrs. Alaska made an 8 pound beef roast and again I cut it in half and we froze it.
When we want a great roast, it will be there and will last for months.
I don't believe that we should throw food out, unless it spoils or the dog won't eat it.
With today's refrigeration and in a tightly sealed container, food will last for well over a week and taste very well.
