The holiday season is in full swing, and that means one thing: leftovers. Lots and lots of leftovers. Whether you still have dishes from Thanksgiving or you’ve started filling up on the first Hanukkah and Christmas parties, it seems like once December arrives, we no sooner clean out our fridges than they fill up with a wall of Tupperware again. While these remnants are great for our frugality, they do make our dinners a little repetitive and boring. That’s why we’re always on the lookout for ways to transform our leftovers and go way, way beyond mere reheating. Our newest favorite? These grab-and-go hand pies that not only use your leftovers, but can be frozen for future fast meals. All you need to make them are your leftovers, some pastry dough, and this video from Martha Stewart.
