We love our canning jars for everything from storing grains in the pantry to shaking cocktails in the park. But by far one of our most favorite ways to use our pint- and quart-sized canning jars is to pack them with salads. Yes, that's right, leafy green salads. Dressing goes on the bottom, veggies and other salad goodies get piled on top. Everything stays separate and dressing-free until you toss the salad together in the bowl — never eat another soggy lunch salad. Even better, these salads last for days in the fridge so we can make a week's worth of lunches ahead of time.
