In a pie pan place the three cups of berries and add the corn starch or tapioca. You can use frozen or fresh berries, whatever you have on hand. Here you can add a tablespoon of maple syrup or honey to sweeten if you prefer.
In a separate bowl, add the oats, walnuts cinnamon, and salt.
Blend in the two eggs and coat all the oats (if you want... add another tablespoon of maple syrup or honey in this step, too)
Cover the berries with the oat mixture and bake for 35-40 minutes or until bubbly. Remove and enjoy! I store mine in the fridge!
