Preheat oven to 325 degrees F. Grease a large cookie sheet and set aside.
In a small bowl, mix together oats, salt and cinnamon. Set aside
Melt the peanut butter and honey (or maple syrup) together until smooth.
Remove from heat and stir in vanilla.
Stir in dry ingredients and mix until well combined.
Spread mixture on prepared cookie sheet.
Bake in the preheated oven for 20-25 minutes, or until granola is lightly browned, stirring the granola once gently half way through. (A great way to test to see if it is done is to remove a small portion of the granola from the pan and set it on the counter. If it hardens as it cools the rest of the granola is done)! The granola can burn quite quickly so be sure to keep an eye on it in the oven. It darkens up once removed so best to take it out once it is slightly browned to ensure you don’t over cook it!
Remove from oven and let sit until cooled.
Once cooled, break apart and enjoy!
