I've been chatting to my SW today, as she has found out what I asked her about.
It seems the EE plan was updated in the New Year, and nobody thought to tell the SWCs in our area (no area manager apparently so they slipped through the cracks).
She has told me that you should have 1/3 of each meal as Superfree, but the rest of it can be all green, all red or a mix of both.
Also, the 1/3 SF rule applies to THE DAY. So if you have a meal which you don't particularly want to add a side salad too, you no longer have to - so long as you have had enough SF during the rest of the day so that overall you will still have had 1/3 SF for that day. Hope that makes sense!
I would imagine SWCs will still be suggesting that you have 1/3 SF with lunch and dinner, and also that it is a good idea to have an element of green and red with each, but you don't HAVE to.
Sorry for any earlier confusion, just passing on the info I was told at the time.
