Do you have lunch plans for tomorrow? You could spend a lot of money on an oversized take-out sandwich, or maybe grab a yogurt on your way out the door in the morning. Or you could pack a satisfying and nutritious lunch.

The answer to your weekday lunchtime doldrums could be in Sunday night’s dinner. Here’s the idea: On Sunday, when you have a little time on your hands, roast a three-pound pork loin. Season it lightly so you can adapt the leftovers to other flavors. Enjoy the warm pork for dinner, then transform the remaining meat into any of the nine exciting lunches here, from Horseradish and Caramelized Onion Pork Sandwiches to Pork and Peanut Noodle Salad. (The leftover pork will keep for two days in the refrigerator.) These robust sandwiches, wraps, and salads are designed to be portable and delicious served cold or at room temperature. And all of them are mouthwatering ways to reinterpret a Sunday-night pork.
