Eating Healthy on Really Tight Budget...How the Hell is this Done?

If you are an expert on this or even have some great ideas PLEASE share! Healthy food is expensive! I am finding it hard to stick to my grocery budget and eat healthy.  I do not buy all organic. I would love to, but it's just not feasible.  There are only three things I always buy organic, milk, eggs, and chicken. This is mainly for my daughter. I don't want her pumped with all the hormones. So this week, I had a lot of canned goods green bean, chick peas, sweet peas, carrots... I made this concoction one day, canned corn, cucumbers, feta, canned artichokes, canned tuna, and red wine vinegar. No matter how good I told myself it was, it really wasn't. It looked like barf and tasted worse. I don't know what I was thinking. So bring on the suggestions please.
