Make your own homemade soups. It's a good way to get a bunch of vegetables that you wouldn't otherwise want to eat. Being part of a soup diminishes the individual tastes of the less palatable vegetables like cauliflower (Yuck!)
Also, get a blender capable of pulverizing fruits and vegetables. You can mix the two and the end result tastes more like fruit juice than vegetable juice. Most blenders come with recipe books. The Jack LaLanne one is actually quite good.
The third option is salads. Start just with a couple of different types of lettuce and dressing. Then slowly add vegetables like carrots and cucumbers. What I used to do was scrap tiny slivers of carrots and other veggies into my salads with a peeler until I got used to them. Soon, I actually wanted them in my salads. Add a can of tuna to the salad. Throw in some fresh cashews, walnuts or almonds. Top with a oil/vinegar based dressing. Make your own with healthy oils and vinegar. Add some pepper, a little salt, and some garlic powder. Mix well.
