In a large bowl, toss the fruit, lemon juice and tapioca flour or starch. Spread the mixture on the bottom of whatever dish you are preparing it in.
In the same bowl, whisk together the oats, almond flour or meal, nuts, cinnamon, ginger and salt. Add the maple syrup and oil, stir everything to combine.
Spread the oat mixture evenly over the berry mixture.
Place in the center of the oven and bake until the topping is golden brown and the fruit is bubbling. This should take 25 to 30 minutes. If the berries were frozen, add an extra 10 minutes.
