Buy Big, Freeze Small

Buying meat in the "family packs" is almost always cheaper. I buy the small freezer bags so I can freeze in portions that I will use later. I wrap each chicken breast (for example) in plastic wrap and then put the pieces into one or two gallon freezer bags. Since each piece of meat is wrapped in plastic, they don't stick together when they freeze and they are also less likely to get freezer burn. Then I can pull out exactly how much I want and don't have too much or too little.
