about 220cals? id need 20 packs a day ??? i tend to get through 3-4000 cals a day but then i have a fast metabolism so its a no go for me.
having one of the meaty ones and topping up with pasta then flapjack might work.
I tried one of these and was not too impressed. It left a wierd after taste and I kept burping all day and tasting it again (it was a bit like a rancid chemical garlic taste).
Shame really as they looked good - I still have a few different ones but am not in a hurry to try them.
