I questioned my C about this as I too struggle to get the s/free foods onto my plate if it doesn't 'go' with the meal, and she said it didn't have to be on the same plate but, at the same meal. So, on those times when I can't get it onto the plate, I usually eat some S/free fruit before I eat my main meal. I eat it before so that I don't eat too much of the main meal and have no room for my super free food after.
