MiracleWare Mini Steamer by Progressive. Nothing brings out flavor of the garden better than perfectly steamed vegetables. Our MiracleWare Mini Steamer is just the right size for a single serving. Steams up to two cups of fresh or frozen vegetables right in the microwave, so you can serve up all the healthy vegetables you need. Culinary Note: Vegetables that are microwaved retain more nutrients than vegetables that are boiled, steamed, or baked.
