I've been served Thermomix food and it was extremely unimpressive. I don't know how easy it was to make though, since I didn't participate in the cooking. I can just say that if it's any harder than microwaving it's probably not worth it.
Our Thermomix is in use everyday, and we love it, but it's not a device for the clueless or careless. Thermomix food is like any other food, the quality is entirely down to the recipe and person cooking it.
