Steaming is the same whether it's in a microwave or in a basket steamer over a pot of boiling water. Boiling is not as good, because it leaches out some of the vitamins in the veggies, which then go into the water. Veggies that come out of the microwave looking dead and limp were cooked too long! You can get the same results in a basket steamer, but of course that's not what you want.
