While making bars at home from hand picked ingredients is the best option, albeit, the most labor intensive option as well, Pro Bar has some good products out there. A "meal replacement" bar with 350+ calories, a protein bar and an energy bar. Some of the marketing states organic, whole grain, etc., etc. Gets high marks and good reviews from lots of Amazon customers.

I suppose just another option to store bought bars but seems better than the ones filled with sugar and no substance.
