I never ate healthier than when I was flat broke. Rice and beans bought in bulk. Potatoes. Chicken breasts bought in large quantities while on sale, and then frozen. Oats. Milk. Eggs. Whichever fruits and veggies are on sale. No one used to believe me when I told them how little it cost to feed our family. It probably helped that we were one of the few families without an obese member or five. But, smart shopping helped a lot too.
