On the other hand, it's harder to save money when you're cooking for two unless you want to eat leftovers all week (which we do for lunch sometimes). Theyjack up the prices of small portions at any grocery store in a middle class area (Safeway has three "tiers" based on how much they think they can soak you for). Spices, fresh vegetables, dairy products, etc all have a limited shelf life. So small portions that are just enough for a meal can be a great idea.
I just bought a whole packer brisket since it was on sale for $2.99 a pound. I'm not really saving money, but my friends are going to eat well!
