A couple weekends ago we were heading out of town for a few days but we had all these vegetables in the fridge. It seemed a waste to chance they would last, so I decided to cut them up and create two stir fry freezer packs. Freezing meat and vegetables is great way to not only save money but time because you always have items on hand for meals.
I buy bulk meat from Costco and freeze it. I find it is cost effective and there is always enough for weekday meals.
The key is to get really good freezer bags or to invest in a vacuum packer, they start at around a $100 but they not only seal the bag but suck all the air out so the freezer items will last longer and not get freezer burnt.
This is one simple way to create less waste, simple freezer meals and save money.
