In a food processor, combine all ingredients & pulse until a fine mixture forms
Add more coconut oil if the mixture is too dry (it should look moist, but not wet)
Using your fingers, form small rectangular bars with about 1 spoonful of the mixture for each
Put the remaining pistachio crumbs in a small sandwich bag
Add the bars one at a time to the bag & shake it so the pistachio crumbs cover each bar
Store in the fridge
