Mix blueberries with sugar, flour, lemon juice, and salt in a baking dish.
Combine flour, oats, sugar, and salt, then stir in melted butter.
The melted butter helps the flour and oats stick together.
Spread the crumble topping over the blueberry filling.
Cook until juices thicken and the topping is golden brown.
Cool for 10 minutes and enjoy with ice cream or whipped cream.
