Some of my staples.
I have access to Sam's, Walmart, got lucky and made friends with a guy that is kin to a local farm.
I buy large fresh, never sodium injected boneless chicken breast at $1.88 per lb from the local farmer, best deal I've found. I also buy fresh large organic eggs at 1.50 per dozen from the same source. Big difference with these eggs from your generic white mass produced variety at most stores.
I buy a 25lb bag of basmati long grain rice for 20 and some change from Sams, clean carb source for months.
Obviously oats are a staple, I buy in bulk at Sams.
1 or 2 days a week I will switch it up and brown a big batch of lean beef and eat it with cubed red potatoes, black beans, spinach leaves.
I yea, I buy large bags of dry black beans from sams, dirt cheap, healthy, stretches for many meals.
Im fortunate to live near bumfukegypt and a amish colony, for much of the spring/summer/fall I get a variety of fruit and veggies for dirt cheap again. One of my staples is raw beets From the amish. I can get a bundle for 50 cents, rediculous value for a true power food.
I don't budget I will admit that so I'm not sure what I spend per month. I do know a big key is to eat out little to zilch. For the price of your average garbage value meal from Hardee's I can purchase a few days worth of healthful nutrient dense chicken breast and a dozen farm fresh eggs to boot. I boil these a lot and snack on them throughout the day. The protein adds up
