For the most part I use metal mixing bowls in the kitchen, mostly sourced from restaurant supply stores. But a couple years ago OXO sent me a set of their plastic nesting bowls, each with a lid and colander. I didn't know if I would hang on to them, but they've become a staple in my kitchen. I like the nonskid bottoms, and the fact that their lids turn them into easy storage containers. The green-blue Seaglass color doesn't hurt, either.
