@mj_1969 I second the warehouse club answer. I buy a package of cartoned egg whites for less than 10 bucks and lots of boneless, skinless thighs. They last me a while and are really versatile.
@dikaioumenoi I just discovered Barebells protein bars. The caramel cashew, creamy crisp, and cookies and cream are my favorites, but all are pretty good. They can be found at Trader Joe's for $1.99 each if you wanna try at a low price.
In terms of eating, I've been sticking to 1300 - 1400...
