Ree Drummond has a half-empty nest while her daughters are off at college, but she still needs good, hearty food at her fingertips for her hungry teenage sons. So she's cooking up dishes that she can serve half now and freeze the rest for another time. She starts with Shrimp Scampi Stuffed Shells and a Nacho Cheese Casserole. Then she assembles a Ranch Pizza Pie and goes low and slow with her Slow Cooker Drip Beef Sandwiches.
