I know what you mean, it's pretty difficult to plan all those meals and than you have to prepare them and also pay for them.
But like Deneb said it's a routine, I somehow managed to come near to those 5-6 meals a day. Since I stopped training for about a month I've lost my routine and almost forgot all the great ideas i've had about my meal plan
Now I'm planning something like this breakfast with musli and peanut butter, than later banana and protein shake (if I buy it), after that comes lunch, than there is some light pre-workout meal, after workout I take protein shake and banana, and after that I have dinner (tuna and low fat cheese).
