I roast lots of veggies, have done carrots, parsnips, beets, sweet potatoes, onions, green beans, broccoli, etc... I like them that way, but dh prefers them steamed. I am so bored with steamed veggies. I do not roast much in the summer, so good idea on the cookie sheet in the grill, mfamom. Missed that post before.
Got a head of cauliflower at the store last night. At another forum I frequent, there is much low carb discussion. Many folks there chop the cauliflower finely in the food processor and use it as rice. saute it a bit with some diced veggies and make it like a pilaf or use it as bed of rice for another dish, like a stir fry or stew. I have not tried that yet.
I did once try cauli mash(as a sub for mashed potatoes) and did not care for it.
