Flourless Brown Sugar Apple Crisp with Hazelnuts

Preheat the oven to 375 Degrees F. In a food processor, pulse butter, oats, hazelnuts or any nut, dark brown sugar, and ½ teaspoon salt until more smooth but not totally puréed. It should look like coarse sand. In a buttered 9x13 baking dish (or sprayed with nonstick spray) toss cut apples with cinnamon, pinch of salt, orange zest and juice, and 1 tablespoon sugar. Cover apples fully with the topping, patting it down evenly. Bake for 40-50 minutes until apples are tender and topping is browned. Let sit for at least 10 minutes before serving with ice cream or whipped cream.
