Tima’s Tips
Slice your chicken against the grain to ensure it stays tender after quick pan-searing.
You can slice the onions and peppers in advance and store them in the refrigerator until you are ready to cook.
Serving Suggestions
This sandwich is substantial enough to stand alone, but it pairs well with a simple side of kettle chips or a light cucumber salad.
Variations
Add a slice of provolone or swiss cheese to the rolls before adding the hot filling to let it melt slightly.
For a bit of heat, stir in a pinch of red pepper flakes when cooking the vegetables.
If you prefer a creamier sandwich, spread a thin layer of mayonnaise or garlic aioli on the rolls before adding the lettuce.
Storage
Store any leftover chicken and vegetable mixture in an airtight container in the refrigerator for up to two days. Reheat in a skillet over medium heat before assembling fresh sandwiches.
Common Questions I Get
Can I use chicken thighs instead of breasts?
Yes, chicken thighs will work well and stay juicy, though you may need to trim any excess fat before slicing.
Is there a substitute for Worcestershire sauce?
You can use a splash of soy sauce or balsamic vinegar if you do not have Worcestershire sauce on hand.
Can I make this sandwich ahead of time?
It is best to assemble the sandwiches right before eating so the bread stays fresh and the lettuce remains crisp.
