To make the crisp topping: in a small bowl, mix all ingredients together with a fork until all the ingredients are well mixed. Place in the fridge while preparing the filling.
In a small bowl, toss all the filling ingredients together. Lightly grease a small baking dish (mine was about 6 inches in diameter, about 2 inches deep). Pour the filling and all the juices in the baking dish and top with the chilled crisp topping.
Place the baking dish on a baking sheet to catch any overflow and place in the oven. Bake for 40-45 minutes until the topping is golden brown and the filling is bubbling. Allow to cool on a rack for 15-20 minutes before serving.
