I switched out the quinoa for barley as my family prefers that. Everything was good - good seasoning and flavor. I particularly liked the lemon. I will say, however, that this is a very light meal. It was healthy but I felt quite hungry a little after dinner.
We eat quinoa regularly. The important thing to remember is not to overcook. It can go from perfect to mush instantly. We like it about 14 minutes so it has a bite to it. Some directions say to cook it for 20 minutes, and I've had people who hate quinoa, and loved it when I suggested they cook it less time. The veggies are all whole in the pic, I can't imagine not cutting them into dice or bite-size pieces. All in all this would be a good dish, and any vegetable will do for roasting.
