Works like a dream with frozen veggies! I got this because I hate boiling veggies and roasting takes too much time. This takes up very little space and you can have perfectly steamed veg in a few minutes.
Put a few tablespoons of water in the bottom part and frozen veggies on the screen part, salt and pepper, and microwave on high for 3 minutes and it's perfect! Works amazing with frozen string beans and frozen broccoli.
