Amen. Poverty does wonders for one's appetite!
During my poorest time? Store brand bologna, thrift store bread and water. No cheese, no condiments.
Even now, when things are extremely tight, I stretch our milk with powdered milk (the family has no idea, so this is between you and me) and we buy ground turkey at Aldi's for 79 cents a pound... eaten in Hamburger Helper or spaghetti sauce, you can't really tell it's not beef.
Aldi's is a great place to shop on a budget. I wish that we had one close, but I have to wait until we go to the city.
