Combine the nut butter, garlic oil, tamari, sriracha, maple syrup and ginger in a small bowl. Add the nut butter mixture, and combine thoroughly until broccoli is fully coated.
Spread parchment paper over a large cookie sheet, and spread broccoli evenly in a single across the parchment paper. It's best when there is space between each piece of broccoli.
Bake for 10 minutes. Remove the cookie sheet from the oven, flip each piece of broccoli. Return the cookie sheet to the oven and bake 10 more minutes.
