You don't have to have superfree at every meal, funnily enough (at least I am pretty sure you don't have to). If I am at home and having breakfast i will have a full breakfast with tons of toms and mushrooms so that takes care of the superfree. If I am at uni I will have fruit and yoghourt.
I used to follow green days, and regardless of how much I love veg, heaping it on a plate day in and day out would drive me insane. So instead I make superfree soup and blitz it. I will have a bowl of this before my meal that way I am getting more veg and it fills me up so my main meal is a little smaller than if I wasn't having soup. I still add veg to the plate, but I don't worry too much if it's not 1/3 as I will have had a decent amount from the soup.
I will have a bowl of soup before lunch as well if I am home, or I will take the soup with me to uni. I think as long as you get a decent amount of superfree (and this includes fruit such as snacks or topping on a meringue and yoghurt) then you should be fine.
Soup is how I cheat in a sense and apparently a lot of people do it this way. Get friendly with a stock pot and a hand blender!
