I bought two packs of bone-in chicken breast that was on sale at my local supermarket.
I tend to separate the meat into freezer bags and not freeze the entire pack. This way, if I need one or two chicken breasts for a dish, I take out only one or two bags instead of defrosting the entire pack and re-freezing what is remaining.
Because this pack had bones, I separated the bones from the meat. I use the bones for other things like stews or soups - where I only need the flavour of the meat.
On freezer bags, I write down what the item is inside as well as the date of when I froze it. This helps me keep track of when the meat was bought and I can use older meat first. All about food rotation to keep freshness!
I place two chicken breasts in each bag, since I tend to use two chicken breasts per dish I make.
You can always buy in bulk and store the rest in your pantry or freezer with other items that come on sale as well. This is a great way to save on groceries while saving some time from having to run to the store each time you need an item..
