I love this type of list. I'm frugal, super busy (read: lazy), and powerlift so I try to make a minimum-cost, high-protein, easy meal-prep every week. Having a high protein / calorie ratio is primary, but keeping it low-cost is a close second. I normally use a pressure cooker, 5-6 lbs of chicken breast, brown rice, and lots of veggies. It may sound boring, but it's great when you add stuff like chickpeas, delicious sauces / salsas, and try out different regional styles of cuisine. Check out the author's protein / dollar list - it's very helpful for the protein-obsessed.
