Spray a 15X10 baking sheet (jelly roll pan) with nonstick cooking spray
In a large bowl combine all dry ingredients, oats, flour, brown sugar, almond slices, cinnamon, and nutmeg
In a microwave safe bowl combine wet ingredients, honey, butter, peanut butter (if using) and microwave until butter is melted. Stir and then add vanilla.
Pour melted mixture over oat mixture, stir well
Spread into your baking dish and make sure it is spread out well.
Bake for 70-75 minutes, stir or flip half way through. Towards the end it will smell a little too done but mine has always been fine.
When its finished it will still be a little soft, stir and break it up a couple times as its cooling and it will crisp up. I store mine in a gallon size Ziploc bag but any air tight container will work.
You can add dried fruit at this point as you are mixing it up!
