Preheat a grill or grill pan over medium-high heat.
Grill the chicken breasts for about 6-7 minutes on each side or until fully cooked and no longer pink inside. Let the chicken rest for a few minutes, then slice it thinly.
Prepare the Bread:
Slice the Subway-style rolls lengthwise but not all the way through, creating a hinge.
Toast the bread lightly on a grill or in a toaster oven if desired.
Assemble the Sandwiches:
Spread mayonnaise and mustard evenly on both sides of the bread.
Layer the shredded lettuce, sliced tomato, cucumber, red onion, and pickles on the bottom half of each roll.
Place the sliced grilled chicken on top of the vegetables.
Add cheddar cheese slices on top of the chicken.
Add optional toppings like avocado slices, jalapeños, and chipotle sauce for extra flavor.
Finish and Serve:
Close the sandwich by folding the top half of the bread over the fillings.
Press down gently to secure the ingredients.
Cut the sandwiches in half for easier handling.
Enjoy your homemade Chicken Subway Sandwich, loaded with fresh vegetables, flavorful grilled chicken, and delicious sauces!
