Rhubarb Raspberry Crisp

Heat oven to 350 degrees. Combine rhubarb, granulated sugar, and orange zest and juice in a large bowl. Stir to combine.

In another bowl, combine flour, brown sugar, and cinnamon. Rub butter into flour mixture with your fingers until it is well incorporated and large crumbs form. Add oats and nuts and combine.

Turn rhubarb into a 1 1/2-quart baking dish, scatter raspberries evenly over surface, and cover with crumb topping. Bake until topping is brown and crisp and juices are bubbling, about 45 minutes. Let cool slightly before serving.
