Recipe Tips
- Make Ahead: You can prepare the chicken 1–2 days in advance. Store it in the refrigerator in an airtight container, and it will be ready when you need it.

- Pairings: This sandwich pairs well with a simple green salad dressed with vinaigrette or a side of chips for added crunch.
- Storage: Leftover sandwiches can be stored in the refrigerator for up to 2 days, though they are best enjoyed fresh.

FAQs
Can I use a different type of cheese?
A1: Absolutely! While mozzarella melts beautifully, you can also try provolone, gouda, or even a sharp cheddar for a different flavor profile.
Toasting the bread in the oven before adding the toppings helps create a crispy base, which prevents sogginess from the chicken and tomatoes.
Yes! Leftover rotisserie chicken works perfectly for this recipe and can save you even more time during preparation.
