Enter the Mason Jar Salad. Mason jars are a choice vessel for layering colorful, nutritious veggies. You probably already have some hanging around in your kitchen. They're the perfect size for a single portion (a pint-and-a-half canning jar or larger works best for fitting all the greens and toppings). And if you layer your ingredients right, you'll end up with a fresh and delicious, not to mention pretty darn good-looking, salad. But the best part is you can easily pack several salad jars at once and keep them in your fridge for lunch all week.

Layer hearty vegetables, such as cucumbers, onions, tomatoes, radishes, peppers, corn, broccoli and edamame-any sturdy ingredients that will hold up well even if they are touching the dressing.

Load up on your favorite protein, such as chicken, shrimp, cheese, nuts, chickpeas, hard-boiled egg or tofu. Whatever your choice, keep it fresh by layering it on top.
