Tomatoes can be expensive once summer is over. During the summer, tomatoes are less expensive and easy to find at the farmers market. Place extra cherry tomatoes in a plastic freezer bag and use a straw to suck out the extra air before fully closing. Remember the bag will stay the shape you put it in your freezer, so make sure the bag is as flat as possible to avoid the tomatoes freezing together. Use these during the winter when cherry tomatoes are more expensive to buy at the store.
