Roughly chop approximately 2-3 cups of feijoa flesh and pop it in the bottom of the greased oven proof dish.
Add vanilla and honey to the fruit and mix through.
In a food processor place the oats, almonds, flour, brown sugar and butter, blitz until you have a nice crumbly topping.
Top the fruit with the crumble topping, bake for approximately 20 mins until the feijoa crumble is golden and crunchy.
Serve with a little vanilla ice cream, cream, yoghurt or custard.
Notes
Tips
Don't skip greasing the baking dish with a little butter before adding the fruit. This isn't so much to stop the fruit sticking, what it does is create caramelised fruit juices, the combination of the fruit, butter, and a little honey adds yummy caramel flavours to the crumble.
Cook the crumble in the middle of the oven, don't use the top racks, otherwise, the crumble topping can cook more quickly than the fruit.
Substitutes
Honey: the honey can be substituted for maple syrup or a little sugar.
Feijoas: As this is a feijoa crumble I'd advise using at least some feijoas, but you can definitely combine the feijoas with stewed apples if you don't have quite enough feijoas.
Butter: This recipe will work with dairy-free margarine or coconut oil.
Flour: This can be substituted for any gluten-free flour if needed.
Brown sugar: This can be substituted for any granulated sugar.
Almonds: I love to add nuts to my crumble, I like the little bit of extra plant-based nutrition they add, you can sub them for any nuts, or leave them out if you wish.
