You may also want to take the time to cut down some of your favorite recipes so that they have smaller yields. However, if it is a recipe that you like and it freezes well, go ahead and make the entire recipe and divide it into separate portions and freeze. Small plastic food storage bags are a good size for one portion. Place all of the individual servings into a larger freezer bag so that they are not lost in the freezer. Remember to date and label each item so that it is easy to identify later.
Meats are often pre-packaged into family sizes.
If you would like a particular meat and it is not available in a quantity you would like, feel free to ask someone at the meat counter to split the package. Most reputable markets will be more than happy to do this for you. You can do the same thing with loaves of bread. Bread freezes very well and thaws quickly. Just grab a couple of slices out of the freezer when you need it.
