Place oats nuts and seeds on baking sheet and toast for 10 minutes.
Prepare 9×13 glass dish by lining with unbleached parchment paper.
Mix peanut butter and honey until well incorporated and set aside.
When toasted nuts and oats have cooled enough to handle, pour into a medium sized mixing bowl. IF OATS AND NUTS HAVEN'T COOLED, THE CHOCOLATE CHIPS WILL MELT WHEN YOU MIX THEM IN. Add in dried fruit, chocolate chips, ground flax, cinnamon and salt in large bowl and mix together.
Pour nut butter mixture over oats/nuts and stir until well incorporated. Batter will be VERY sticky. You may think there isn't enough of the nut butter paste, but keep mixing and you'll see it is exactly the right amount.
Spread batter into prepared pan. Use another piece of parchment paper to cover the mixture and then use your hands to press down until it's evenly distributed all the way to the edges. Use the bottom of a bowl or measuring cup to firmly press down. This is super important. You want the mixture to be as compacted as possible before baking so it won't fall apart when you try to cut it.
Bake for 25 minutes, until golden.
Allow to cool COMPLETELY in the pan. Lift parchment edges to transfer to a cutting board.
Cut into bars and store in covered container at room temperature for up to 1 week or in the freezer for up to 3 months.
Notes
HONEY: Use date syrup or maple syrup for a truly vegan bar. NUTS: Use 1 cup total, any variety or combination. I used ½ chopped walnuts and ½ sliced almonds. If nuts are larger, chop into small pieces. Pecans, hazelnuts, or cashews will also work well. What type of nuts and how finely you chop them will depend on your audience. Do you have nut and crunch lovers? Or are you trying to hide the nuts to gain nutritional value and still please your picky eater? DRIED FRUIT: I used a combination of chopped dried cherries and dried figs,cut into small pieces. Golden raising, apricots, cranberries would all work. Look for unsulfured and unsweetened dried fruit, and cut large pieces into small bits. PEANUT BUTTER: Any drippy nut butter will work in this recipe. I often use almond or cashew butter and have used walnut butter with great results.
