Preheat your oven to 375°F (190°C).
In a mixing bowl, combine the flour, oats, brown sugar, cinnamon, and salt.
Add the melted butter to the mixture and stir until it becomes crumbly.
Take a 9x9 inch baking dish and spread the cherry pie filling evenly across the bottom.
Sprinkle the crumbly mixture on top of the cherry pie filling.
Place the baking dish in the oven and bake for 25-30 minutes or until the top becomes golden brown and the filling is bubbling.
Take the cherry crisp out of the oven and let it cool for a few minutes before serving.
Serve warm with a scoop of vanilla ice cream.
