If starting with whole oats and whole wheat berries, you’ll need to roll them first. If starting with rolled oats, move to step 4.
Add oats, wheat berries, barley and quinoa to the oat roller.
Place a bowl under the roller and turn it on. Process the breakfast mix until everything has run through the machine.
Stir to combine oats and other ingredients together.
Add chia seeds, nuts, dried fruit, and spices and stir to combine.
If using dry sweetener, add it to the mixture at this time.
Using a funnel, pour mix into a jar or other storage container and seal.
Store in the freezer (or pantry for store-bought oats).
