Summarize the following:
You'll also need to make sure that you have the appropriate types of storage containers. If you're preparing any type of meal in advance, you'll need to figure out how you're planning to store it safely.  Tupperware containers are a great tool when you're making meals in advance. Most keep foods fresh in the refrigerator and many are also freezer and microwave safe. Mason jars are a more artistic and unique way to store food. The screw-on lids provide an airtight seal. This is great for items like yogurt, oatmeal or cottage cheese. Aluminum foil or plastic wrap can help keep foods fresh in the refrigerator. They're not airtight and can leak so make sure to only use these on solid foods-like an egg sandwich. It's nice to be able to pull out a nutritious breakfast right from the fridge; however, you can't store pre-cooked food for days on end.  Choose the best option for your meal storage-refrigerator or freezer.  Many breakfasts that you'll make might be for the next morning; however, some recipes allow you to make multiple servings that can last you all week. Only make enough servings to last you for about five breakfasts. If you make more you'll need to freeze it. Only freeze items like egg sandwiches, chia seed puddings, smoothies (blend the frozen smoothie to make smooth again), or oatmeal. Items like yogurt won't freeze well. If you're choosing to store foods in the refrigerator, store them above any raw meat or seafood. All cooked foods should be stored near the top of the refrigerator where liquids or juices from raw foods cannot contaminate them. If you're short on time in the morning, even for a quick reheat in the microwave, consider bringing your breakfast to your office instead.  Keep your meal cool during transportation to work. This is especially important if you have a fairly long commute. You do not want your food getting too warm this increases the risk that harmful bacteria will grow. Use an insulated lunch bag to pack your breakfast. Place a freezer pack or frozen water bottle in your lunch bag to keep your breakfast cold prior to getting to your office. If you're bringing a liquid to work like milk for your cereal consider putting the liquid in a thermos to keep it at the appropriate temperature. Only juices, milk, non-dairy milk or smoothies need to be kept cold.

Summary:
Get the right type of storage containers. Choose between the refrigerator and freezer. Pack your breakfast safely.
