Canned chicken, canned tuna, and I get the regular Myoplex shakes for $1.25 each. They have 42g protien. Frozen boneless skinnless chicken breast is a good value too. I always buy Tyson. A little more expensive, but the quality is sooooo much better. Eggs are cheap too. I eat 8 whites and 2 yolks every morning with s scoop of Opt.Nutr. protien.
I had to do something about controlling costs. My wife was going berzerk. Now she is a little better now that I have found cheaper solutions and I cook in bulk to last me a week.
Yes the diet is the most expensive part for sure.
