One quick snack, I enjoy having is blue cheese on whole wheat crackers. It is a simple snack but taste great. Blue cheese have an earth taste that I enjoy. Blue cheese is know for blue veins of mold that runs through the cheese. Sometimes, I will get some Gorgonzola cheese which is another type of blue cheese which has a more potent taste.
I hope you give this quick and simple snack idea. Try different types of blue cheese. Some have a mild taste, while other are more potent.
