Soak the buckwheat groats overnight
Preheat oven to 300 degrees
Lightly spray a large baking sheet with a high smoke point oil (see notes). Drain the soaked buckwheat and spread evenly on the baking sheet
Bake for 40 minutes, stirring the groats half-way through
Add the remaining ingredients and stir well.
Bake everything together for another 20 minutes.
Let cool and enjoy!
[I use avocado oil spray because it has healthy fats and has a higher smoke point than some other healthy oils (like EVOO)]
