Prepare a 9x13 baking dish by lining it with parchment paper, extending the paper over the edges. Have that close and ready.
In a large mixing bowl, combine the dry ingredients: nuts/seeds, oats, crispy rice, dried fruit, flax/hemp/sesame and kale chips, if using.
In a small saucepan, combine the wet ingredients: coconut oil, tahini, molasses/maple syrup, coconut sugar, vanilla, salt and herbs, if making savory bars.
Bring to a boil over medium heat, reduce heat to low and simmer for 3 minutes, while stirring constantly. It should be bubbling as you stir.
Being careful not to burn yourself, pour into the oat mixture and stir quickly to coat everything.
Transfer mixture to the prepared pan and use another sheet of parchment to cover mixture and press the mixture evenly into the pan. It is also effective to use the flat bottom of a measuring cup or rolling pin to evenly press down the mixture.
For chewy bars, place pan in the refrigerator to chill.
When completely cooled, cut and store refrigerated for two weeks. Freeze for longer life and individually wrap for a quick snack to grab on the go.
For crispy bars, bake at 350 degrees for 20 minutes. Cool and cut into bars.
