Egg, Avocado, and Cheddar Homemade "Hot Pockets"

Preheat oven to 350 degrees F and line a baking sheet with parchment paper. On a floured work surface, roll out pie crust into a large rectangle and slice off rounded edges (if using store-bought). Slice into four strips. In a large nonstick skillet, pour in beaten eggs, season with salt and pepper, and scramble, 3 minutes. Spoon over bottom halves of pie crust. Top with avocado and cheddar and fold over tops. Use your fingers to pinch to seal and press the twines of a fork to crimp. Brush with egg wash and transfer to prepared baking sheet. Bake until golden and puffy, 18 to 20 minutes.
