Here's my suggestion for buying meat:
Never, ever buy meat.
It's ok to eat meat if it's offered to you for free, like at a party, or as part of the free snack at Costco. I just had a delicious free sample of top sirloin at Berkeley Bowl. ($7.99 a pound to purchase - Do Not Purchase!)
One pound of hamburger costs, like, three bucks!!! That plus some vegetables and bread will only make two meals! For about the price of one pound of hamburger you could have twenty hearty bowls of Bean-Lentil soup!!!! For one pound of top sirloin you could have fifty-five bowls of Bean-Lentil soup!!!!
Two dollars - Price of meal with hamburger
18 cents - Price of meal of Bean-Lentil soup
Savings by not eating meat: 91-96%
I'd rather put that dollar eighty-two into the bank and lentils into my stomach!
There are all those pesky environmental conerns, too. It takes 500 gallons of water and three acres of land to make one lousy pound of hamburger. (Ok, I made those numbers up. It's something like that. Look it up.)
How many green beans could you grow with three acres of land and 500 gallons of water? A LOT!!!! Way more than a pound!!!
