any tips on salvaging leftover cooked meat slightly dry

With chicken or beef, I use the food processer and grind it up. Then mix in mayo, spices or herbs, and serve it as a spread on crackers or make open face sandwiches.

Warm some broth (beef for red meats, chicken for white) and dip slices in broth. Serve on toasted rolls with cheese melted on top and broth on the side.

Or you could cut it up/ dice it and use in some sort of mixed dish-say a rice dish or taco filling- if you're into improv.

Serve warm in a braise (wet). Gravy or wine or soup.
Serve cold as a sandwich with mayonnaise or salad dressing on the bread.
