You don't need a steaming bag to microwave veggies. I just use a microwave safe container with a lid (not one that seals airtight) like corning ware. Frozen veggies microwave up just fine and taste almost steamed cooked that way. I like a mixture of costco's frozen broccoli mixed up with some fresh sliced onion, green pepper and grated carrot. I can easily eat 3 cups of that along with a chicken breast and I'm full.
