These single-use microwave steam bags are fantastic. Just fill with frozen vegetables, (or fish or chicken). Place in the microwave for a few minutes and VIOLA! delicious, healthy, steamed veg! You get 30 bags in the pack and each bag holds about 2– 4 servings (vegetables) 1–2 servings (chicken or fish). Why buy those pre-packaged steam microwaveable frozen vege's at the Supermarket (3× 150g bags) for $5– when you can buy this pack of 30 bags for around the same price, and fill it with veg, fish or chicken of your choice. Highly recommend!
