Butter a glass baking dish and add the chopped fruit to the dish.
In a mixing bowl, combine the oats, almond flour, butter, walnuts (or pecans), sweetener of choice, cinnamon, and salt. Mix well until the butter is distributed.
Sprinkle this mixture evenly over the top of the fruit.
Bake at 350 F (180 C) for 40-45 minutes, until the fruit is bubbling and the top is golden.
Serve with fresh whipped cream or vanilla ice cream. Enjoy!
