Directions

1. Chill butter, cut into 1/2-inch pieces, and nearly freeze water. Slice rhubarb 1/2 inch thick on a sharp diagonal. Hull and halve strawberries. Grate nutmeg.
2. For crust: Blend oats, sugar, brown sugar, and cinnamon in a medium bowl. Add butter and shortening, rubbing between fingertips until mixture resembles coarse meal. Mix in vanilla. Gradually add water by tablespoons to bind dough. Form into a ball; flatten into a disk. Wrap in plastic and refrigerate at least 30 minutes.
3. Roll out dough between sheets of lightly floured waxed paper to 1/8-inch-thick round. Trim to 12-inch round and transfer to a 9 1/2-inch deep-dish glass pie dish. Trim overhang to 1/2 inch and crimp edges. Refrigerate 20 minutes.
4. Preheat oven to 350°F. Line crust with parchment or foil, fill with pie weights, and bake until set, about 15 minutes. Remove weights, brush crust with glaze, sprinkle with 2 tablespoons oats, and bake until light brown, about 20 minutes. Cool completely.
5. Increase oven temperature to 375°F. For topping: Combine oats, flour, sugar, and cinnamon in a food processor. Add butter and cut in until crumbly. Stir in remaining oats.
6. For filling: Mix rhubarb, strawberries, sugar, cornstarch, cinnamon, and nutmeg. Let stand 30 minutes, then bring to boil over medium heat, stirring constantly. Simmer until juices thicken, about 3 minutes.
7. Pour filling into prepared crust. Cover with topping and bake 20 minutes. If using pastry leaves, arrange around edge and brush with glaze. Bake until topping and leaves are golden and juices bubble, about 15 minutes longer. Cool on rack.
