sdf nailed it. Eggs by the master case, tuna, meats. I get 60-100g just from pre/post workout shakes. Tho, I don't buy any shakes, I make mine from bulk powders. Down the line you can buy sacs of protein from 3-9 bucks a pound.

An easy way to add in protein... add another meal. Add slowly and you will get there.

I eat from 5-7 times per day, depending on wha type of day it is, and what foods are in the fridge. each meel will range from 250-600 cals, so its kinda like snacking all day, which is easy for my situation. desk job.
