Can I use chicken breasts instead of thighs?
Yes, but thighs stay juicier and more flavorful when cooked. If using breasts, pound to even thickness and monitor closely to avoid drying out.
How do I keep the roll from getting soggy?
Toast the roll with garlic butter just before assembly, and avoid letting the finished sandwich sit too long before serving. The crispy breadcrumbs on top also help absorb moisture.
Can I make this ahead?
Prepare the chopped chicken mixture up to 2 days ahead and refrigerate. Assemble and toast the roll fresh right before serving for best texture.
What if I don't have a sub roll?
Use ciabatta, focaccia, or any sturdy sandwich bread. Avoid soft white bread, which will fall apart under the sauce and cheese weight.
Why chopped instead of a whole cutlet?
Chopping ensures every bite has saucy, cheesy chicken mixed throughout rather than layered, giving you consistent flavor and easier eating on a sandwich.
