Mindless Statements and Chatter

Anyone out there got any good and easy ways to maintain lean protein intake.  I have to quit relying on the protein bars and shakes.  Seems I just run out of time to make healthy food during the week and hence resort to Bars and Shakes as meal replacements.  That is fine on occassion, but really need to make it a consistant effort to get other sources of lean proteins.  Anyone know of any good shelf sources that aren't loaded with sodium and preservatives?  With two kids, a crazy work schedule and an alternating schedule from my wife, seems almost impossible to take the time to do up chicken, fish etc... during the week for my lunches and afternoon snacks.
