Gouda cheese adds a delicious element to these sliders. You can use regular Gouda or other similar cheeses such as Edam, Havarti, Fontina, or Monterey Jack. Pepper Jack would be great as well!
We will start off with 1 1/2 pounds of cooked chicken breast, which means this recipe is perfect for using up leftovers. If it's easier for you, feel free to use rotisserie chicken from the store.
