Preheat oven to 180oC.
Combine the honey and orange juice in a medium-sized baking dish. Then mix through the feijoas, diced apple and orange zest.
Combine all crumble ingredients in a bowl and mix together.
Spoon crumble topping over the feijoa and apple filling. Alternatively, you could make mini crumbles in ovenproof ramekins.
Bake until the topping is golden, approximately 30-40 minutes.
Serve with yogurt, custard or ice cream.
