I can't stand any chocolate protein powders... BUT I think you should try the following...... (mix it up)
Vanilla Protein Powder... 2 or 3 scoops
Low/No Fat Fruit Yoghurt
Banana
Half an apple
400ml
Low Fat or Semi-
Skim Milk
Yum... tastes like a smoothie... and gets a meal amount in there too...
You have to use a blender or mixer or whatever... I only use a hand one I carry to work with me... Alternatively, try your own blends... most yoghurts/fruits/veg and milk mix well together (except kiwi fruit)
hope this helps.....
