Hi Jen,
The smoothies I made were made (and sometimes still are) from fresh banana, raw egg, full cream milk, (sometimes yoghurt is added), along with a high fibre and protein dietary supplement powder mixture, icecream, and honey. Very scrumptious, and kept me going all day, heaps of calories.
By the by, I wasn't able to eat/drink anything cold or hot for a long time... room temperature was quite sufficient, and still is.
Cheers!
Tizz
