Pre-heat your oven to 180°C (355°F).
Rub the flour and butter together until coarse crumbs form. You can be fairly rough with it, larger crumbs equals crunchier topping!
Add the desiccated coconut and mix well.
Peal and core the apples and cut into cubes.
Remove the feijoa flesh from the feijoas and roughly chop.
Mix the apple cubes, feijoa flesh, sugar and ginger together in a bowl.
Pour the fruit into a baking dish and top with the crumble topping. Smooth down the topping to form a fairly even layer.
Bake with 45 - 50 minutes or until the top is golden brown and crunchy.
Remove from oven, serve and enjoy! Fabulous with a scoop of my easy vanilla ice cream. Delicious!
