How to Make It
Preheat toaster oven to 400°F. Unroll pie crust onto a lightly floured surface, and cut in half. Roll cut edge out to a slightly circular angle.
Combine pears, brown sugar, cinnamon, and 2 tablespoons flour in a bowl; toss to coat. Place half of the pear mixture in 1 of the crust portions; place remaining half of pear mixture in second crust portion. Sprinkle each with 1 tablespoon of almonds. Wrap edges of dough over fruit mixture forming a 6- to 7-inch crostata. Brush with egg wash.
Place both crostatas on a small rimmed baking sheet lightly coated with baking spray or lined with parchment paper. Bake in preheated oven until golden brown and the fruit is softened, 18 to 20 minutes.
Combine honey and orange zest in a microwavable bowl, and microwave on HIGH 20 seconds. Brush honey mixture over both crostatas. Top with vanilla ice cream, if desired.
