Even though I am a billionaire (ha ha big fat lie) I still buy lots of non-grass-fed meat. I get these really big huge chicken breasts, enormous top sirloin steaks and organ meats from this ethnic market with amazingly reasonable prices. I also keep costs down by buying less produce. I used to throw away so much produce because I'd get so seduced by how pretty it was in the market. I just eat really super simple and plain--every meal is meat and potatoes or meat and veggies. I make fancy stuff now and then for dinner so it's not too boring.
