I think I did buy organic. After we got home and noticed everything said organic. We have made a menu for the next couple of weeks taking left over to work and just eating portion control.
I you mean organic, it probably is more expensive unless you can find a local co-op or market. My answer to cheap, healthy eating is lots of dried beans cooked from scratch. We have some form of beans almost every day. I can do this easily because I'm home all day, but my friend puts them in the crock pot. Haven't tried that, but if you work you might try it.
Remember, the money you spend on your health is the best investment you can make. Kudos to you for the positive steps you've taken.
