I have been doing the freezing myself. Because I work a few days a week I make a double shake the night before. A banana a few strawberries, milk & double the shake mix, blend & into the freezer in goes ready for work the next day. I'll have half at breakfast half at lunchtime.
Heres another thing I'v been trying and I loved it.
2 medium pieces of fruit either canned or fresh into your blender, your shake mix a dash of milk just enough to make it into a paste then mix it into some low fat vanilla or fruit yogurt + a hand full of muesli for some crunch. This is a great alternative to the shake & you can have it either hot or cold. This receipe is with the Admin Censored diet, I'm sure you could change it to suit Tony F or what ever you are doing.
