Steaming has to be the easiest way to cook vegetables. I love the idea of steaming a fresh vegetable and knowing that I do not have any added sodium or preservatives that canned goods contain. It's also economical in most cases. My family eats about 2 lbs of fresh green beans (I have a large family) as a dish and it costs about $3-4 at my local farmer's market. If I use canned green beans, I end up paying $5-8 dollars for the same amount, depending on the store and any sales they may be having. It's a no-brainer. Fresh is best, both for my body and my wallet.
Steaming is easy for busy families, but I think some people are intimated by the process. You could always buy the "steam in the bag" veggies in the frozen food section at the grocery store, but the prices are outrageous. You can steam the same fresh vegetables for the same amount of time for much less! Clean up is just as easy, too.
