Some of the most-popular resolutions are eating healthier, spending less money and getting organized, and you can check all three off your list with one activity. In fact, you can do them all in one day if you plan accordingly, using easy meal prep to make cheap, healthy lunches for the whole week.

Below, we've rounded up some of our favorite lunch recipes that can be packed up in Mason jars at the start of the week to keep you organized and on track for at least five days in a row. Start with a colorful  Soba Noodle-Vegetable Salad, pictured above, and get more healthy lunch ideas here.

Not only will hearty seeds like quinoa fill you up, but they also don't get soggy after sitting in the fridge for a few days. Butternut squash and walnuts add extra texture to the dish, which can be enjoyed hot or cold.

Layer up escarole, giardiniera mix, tomatoes, artichokes, meat and cheese as a savory trifle. The briny dressing can wake you up better than a cup of java.

Mason jars aren't just for salads — they're great for portioning out big helpings of salsa verde-and-cilantro-spiced chicken and bean chili, too.
