Preheat oven to 180C. I used a large pie dish to make mine in (about 24cm).
Mix the fruit and squeeze over lemon, add ginger and vanilla and mix.
Mix the dry ingredients: flour, salt, sugar, oats, coconut - and rub in the coconut oil as you would if it were butter.
Top the fruit with this mixture and bake for 30 minutes.
I allowed myself a very small serving of cream (it is high FODMAP) as I just can't eat crumble without it!
