I love granola bars. However, the ingredients is mostly butter and sugar. So, I did my best to come up with a much healthier version that tastes great.

The heart healthy ingredients include the peanut butter, olive oil, walnuts, seeds and oats.

Walnuts are terrific for keeping the blood vessels elastic. The healthy fats (olive oil, nuts, seeds, peanut butter) help guide your diet to a more Mediterranean pattern, as traditional snacks are often made on butter which contains more saturated fat. Unlike regular granola bars or flapjacks, the sugar mainly comes from the dried fruit rather than refined sugar that lacks nutrients and fibre.
