i do a lot of baby food in the microwave. when you keep the food covered you keep the nutrients and it basically steams. cover off and you lose nutrients. i usually do one or 2 zucchini at a time. depends on how much you have and how soft you want it. I would chop in large pieces, put in a bowl with a little (very small) bit of water (which you later can just mash or puree with so nothing is lost), then on high for 4-5 min. I try to check midway through the cooking time and stir.
mashi's colander suggestion is good too - i steam all the time and i ONLY do it this way! dont have a steamer!
for roasting i roast zucchini chopped in chunks or in strips, tossed with a little olive oil (and s&p if it's for us) and roast at 200C (400ish F) for 20-30 minutes, turning once. i don't do this strictly for dylan's food though it's too labor intensive, only when it's our food anyway and he has some too. x
