Do you know any good veggie-based recipes that even kids will love?

I really enjoy cauliflower rice. http://minimalistbaker.com/how-to-make-cauliflower-rice/ To make these, you simply have to cut out the florets of the cauliflower and put them through the food processor. I would then treat them as "rice" and make fried cauliflower rice by simply frying them with egg. You can also use cauliflower to make mashed cauliflower. Add a little bit of cheese if your child find the taste of cauliflower too overpowering. Enjoy!
