So it is with the micro-steamer.

The absolutely retro Tupperware micro-steamer.
The bottom bowl takes a cup of water, the middle fresh veg. The middle bowl is basically a colander. I use this at least twice each week without a sign of wear. It turns out perfectly steamed veggies from the microwave every, single time.

It may not be the most artful presentation but it is as dependable as a best friend.

Steamed broccoli or asparagus, spinach or any vegetable and I've even cooked chicken and halibut in this. In fact it's perfect for poaching seafood.
