Cast-Iron S’mores Calzone | There’s nothing better than a classic s’mores, but we love coming up with ways you can enjoy the tasty treat sans firepit. To mimic the graham cracker part of the summer staple, we combined graham cracker crumbs with melted butter and salt and brushed it all over a chocolate and marshmallow-filled calzone. As it bakes, the mixture creates a salty graham cracker crust for the calzone, adding delicious crunch. | RealSimple.com
