I was so glad we tried this dish, I bought the broccoli and cauliflower two times before actually making it. It has great flavor and was easy to put together. I added half an onion to the recipe because I LOVE most any dish that starts with sauteing onion and garlic. I used rice penne noodles as well to avoid gluten. I have heard that rice noodles get mushy, so I was careful to pull them off the stove top as soon as they were al dente - actually a little more firm than I usually cook pasta - and they turned out perfect. We had no problems with the noodles breaking or getting mushy and they weren't too hard either.
What I like about this dish is that it is full of vegetables but it doesn't feel like you're eating a plate full of vegetables.
