Preheat oven to 400 degrees. Place the pie shell on a baking sheet.
Cap and halve the berries. Toss in a bowl with the cane sugar, cornstarch and fresh lemon juice.
Spoon the berries into the pie crust.
To make the crumble, combine all dry ingredients. Pour in the melted coconut oil and stir well to combine evenly. Spoon the crumble on top of the strawberries.
Cover with foil, then bake for 30 minutes. Remove foil and cook for another 20 minutes, or until the strawberries and gooey and tender and the crumble topping is golden brown.
Cool slightly before cutting into slices. Serve with your favorite vegan ice cream or whipped cream!
