Preheat the oven to 375 F.
Make the filling: In a large mixing bowl, mix together the berries with the sugar, lemon juice, flour and ginger. Pour the fruit filling into a shallow 2 to 2 1/2-quart baking dish (or large oven-proof skillet!)
Make the topping: In another large bowl, combine the oats, nuts and seeds, hazelnut meal, brown sugar, salt and spices. Add the butter and use your fingers to work the dry ingredients and butter together to form a loose mixture. Sprinkle evenly over the fruit.
Bake for 30 to 35 minutes, or until the crisp is golden brown and bubbling at the edges. Allow to cool 10 minutes before serving. Serve warm. Right out of the pan, or in small bowls topped with ice cream if you’d like.
