Planning is the name of the game here. First, get yourself a nice cooler, I like the collapsible styles best because you can store them easier. And get some blue ice, some ziplock bags and some tupperware and a re-usable bag like the kind you take to the grocery store. You can put the non-cold items in there.
One of the best things to do, is pick one day of the week and get your prep started. You should get a variety of fruits and veggies and do all of the cleaning on this day, and with the veggies you can also cut them up and put them into the larger sized ziplock bags. Fruit tends to go bad quickly after you’ve cut it up, so either leave it whole or wait until the night before to cut it. Some easy veggie favorites: carrots, cauliflower, grape tomatoes, broccoli, radishes. Wash ‘em, cut ‘em up and distribute into large ziplocks. Then they’re ready for you to grab some of each and put them into smaller ziplocks that you’ll put in your cooler to take with you.
Easy fruits (don’t buy more than you will use in 2 weeks or they’ll go bad) : apples, nectarines, strawberries, blueberries, bananas, cherries and grapes. Wash all of them on your prep day, put them in your fridge and grab some before you head out the door in the morning, put them in your cooler with the veggies.
Snacks: all kinds of nuts (which you can divide up into small tupperware bowls on prep day) graham crackers (preferably Trader Joe’s brand which are not full of chemicals and preservatives) you can make peanut butter sandwiches out of them the night before and put them in a small ziplock, dried fruits such as cranberries, apple chips, prunes, raisins, apricots, divide portions into your small ziplocks or tupperware bowls on prep day and grab some on your way out of the house. Whole grain chips and crackers with low sodium (Trader Joe’s make lots of different varieties) put individual portions into ziplock bags on prep day. Grab a bag on the way out the door. Other good snacks include individual sized yogurt cups and apple sauce (Make sure you keep a spoon in your bag). Then find some good whole grain breakfast/energy bars that are not too high in sugar/sodium (I like Kashi brand and Cedar Lane and Soyjoy). And either buy a block of cheese and cut it up and put into individual sized tupperware bowls or get some of those already small sized, pre-packed cheese.
Drinks: individual cartons of milk, yogurt drinks, 100% fruit juice and pure, non sweetened, iced tea, don’t give in to the temptation of articicially flavored sugary drinks or soda.
Get some whole grain bread that you keep in the freezer (stays fresher longer and you can have a lot on hand) and make a cheese sandwich or a peanut butter sandwich (right on the frozen bread slices) the night before and put it in a ziplock bag and put it in the fridge. Grab it on your way out the door.
The trick with all of this is prep, convenience and nutrition. Try to avoid junk food at all cost. Buy what you need, pick a day for preparation so you’ll have everything you need ready to go for the week and then you can just grab and go. Good luck : )
