If it were me I would stretch it to two meals but I guess you might not want to.
You could just make up some gravy, pour it over the slices of pork and heat through gently in the oven, and serve it like a roast again.
Or you could make it into two meals:
Slice two lots of meat very thinly. Make up an Asian broth (Chinese, Thai, Korean or Japanese), slice whatever veg you want in the soup very thinly to match the pork, boil up one egg per person, cut in half and serve everything on top of noodles or rice.
Slice two lots of meat very thinly. Fry onions, garlic and whatever veg you want with similar spices to above for nachos, add the meat, pad out with rice and serve with wraps/tacos or, my favourite, wrapped in lettuce leaves.
Slice two lots of meat very thinly. Fry onion and whatever veg you have, add the meat to warm through, and make sandwiches (if you have baguette/crusty bread/panini even better) with rocket or whatever leaves you have.
