I love raw cabbage - both red and green. Everyone in my family is wild about cucumbers (they also go great into smoothies and gazpachos in the summer!). I also like raw radishes, daikon and reds; raw yam. I also like all tomatoes and peppers raw. Our nightly veggie plate is generally baby carrots, colored pepper, celery, radishes, red cabbage and cucmbers.
Cauliflower I love mushed - I boil it and zoop in a blender with a bit of coconut milk to be a consistency of cream of wheat or thin mushed potato.
I really love broiled zuccini and eggplant chips (ev olive oil and coarse salt).
Did you try and vegetables au gratins? particulary cauliflower.
