The size that started it all, the sandwich is a crowd pleaser and award winner that's perfect for meal prep and litter-free lunch packing. Plus, it's the right size for storing on-the-go essentials like hand sanitizer, tissues, and tiny brushes. A must for every hungry home chef, the half gallon is best suited for large kitchen tasks like freezing portions, marinating meats, and sous vide cooking. Keep it handy for beach trips, too, as it's big enough to hold bulky or messy stuff like a wet swimsuit.
