Chicken: As we mentioned in the post, rotisserie chicken is a quick, easy option for this recipe. But, nearly any boneless, skinless chicken breasts will also work well here, as long as they’re not seasoned with spices or marinades that compete with the other flavors in this recipe. If you prefer, you can simply plan on cooking a couple of extra chicken breasts whenever you’re making chicken, so you'll have extra cooked chicken for this recipe without any extra work.
Hot sauce: We like to use 1/4 cup total for this recipe (which works out to be 3 teaspoons per sandwich). That amount creates a bold, pleasantly spicy "buffalo wing" flavor. However, if you'd like a little less spice and a more "grilled cheesey" flavor, try using a total of 8 teaspoons hot sauce, instead of the full 1/4 cup (which will work out to be 2 teaspoons of hot sauce per sandwich instead of 3 teaspoons). It's also delicious!
Make-ahead steps: You can mix up the "buffalo chicken dip" portion of this recipe (the chicken, cream cheese, hot sauce, and onion) earlier in the day or a day before, so your grilled sandwiches are even quicker to make at mealtime.
