Cheese Spinach and Corn Piroshki

If you can’t choose between this and the spicy pizza version, just make them both. A piroshki party is a very cool thing. The fillings are no-cook and the dough doesn’t require a second rise after shaping, so there’s really no excuse. Aggressively wringing out moisture from the frozen spinach will ensure your piroshki are melty-cheesy, not sad-soggy.
