Recipe for Cheap, Healthy Granola Bars?

I am trying to lose weight and the one thing that seems to stop me is my sweet tooth. I dont really like chips and salty snacks and vegetables dont really satisfy my cravings. So does anyone have a recipe for cheap, healthy granola bars ( or something similarily sweet, cheap and healthy ) that i can snack on instead of unhealthy baked goods that will satisfy my cravings?
