apples, golden delicious or other, medium to soft apples
Sprinkle of cinnamon sugar (optional)
brown sugar, firmly packed

Vanilla ice cream or cream
Prepare the apples by peeling, coring, and chopping into chunky pieces, then place in a grill-proof pan. Sprinkle the caster sugar and cinnamon sugar (if using) over the apples.
In a bowl combine the flour, brown sugar, butter, and oats. Using your fingers, rub the butter through the mixture until you have a very coarse texture. Stir in the walnuts. Sprinkle the crumble topping evenly over the apples in the pan.
Set up your Q for indirect cooking and preheat for 10 minutes.
Place the pan with the apple crumble on the trivet and turn the burner control knob(s) to the roast/bake setting. Close the lid and cook until golden, 30 to 40 minutes.
Spoon the apple crumble into serving bowls. Serve with ice cream or cream.
