Whether you’re meal prepping for the week, boxing up dinner leftovers, or packing a virtuous lunch to eat at your desk, you’re going to need the OXO Good Grips Prep & Go 5-Cup Container. It can hold anything (soup, roasted veggies, saucy pasta, a big salad, for example) and it will not leak—thanks to its watertight lid with silicone gasket and two locking clips. The see-through window will help you spot what you’re looking for and the stay-cool handles make for easy microwave-to-table transport. And, although it looks like a sleek, ceramic container, it’s actually a much lighter BPA-free alternative to single-use plastic. Dishwasher safe. For a secure seal, press firmly in the middle of the lid, then engage the latches; you'll hear air being released as you press the lid down.
