How to Make Chicken Caesar Sub Sandwiches (High Protein Meal Prep Lunch)

1. Preheat your grill or grill pan to medium-high heat (about 400°F). While it heats, brush the chicken breasts with olive oil and season evenly with garlic powder, oregano, salt, and black pepper.
2. Place the chicken breasts on the grill and cook for about 5-6 minutes per side, or until the internal temperature reaches 165°F and the chicken is nicely charred with grill marks.
3. Remove the chicken from the grill and let it rest for 5 minutes. Meanwhile, slice the sub rolls horizontally and lightly toast them on the grill for 1-2 minutes until crisp but not burnt.
4. Slice the grilled chicken breasts thinly. Spread about 2 tablespoons of Caesar dressing on the bottom halves of the toasted sub rolls. Layer with sliced chicken, a handful of chopped romaine, a slice of provolone cheese, and sprinkle with grated Parmesan cheese.
5. Close the sandwiches with the top halves of the rolls, gently press down, and if desired, place back on the grill for 1 minute just to slightly melt the cheese. Serve immediately with lemon wedges for a fresh zest.

Tips for the Best Results

• Use a meat thermometer to ensure perfectly cooked chicken without drying it out.
• For extra flavor, marinate the chicken for 30 minutes in Caesar dressing before grilling.
• Choose fresh, crunchy romaine for the ideal Caesar salad texture inside the sub.
• Toast your sub rolls just enough to hold up against the moist ingredients without getting soggy.
• Feel free to swap provolone for mozzarella or Swiss cheese for a different melt and taste.

Storage and Reheating

Store any leftover Chicken Caesar Sub sandwiches wrapped tightly in foil or plastic wrap in the refrigerator for up to 3 days. To keep the bread from getting soggy, consider packing the chicken and lettuce separately and assembling right before eating.

To reheat, unwrap the sandwich and warm it in a preheated oven at 350°F for about 10 minutes, or until heated through and the cheese is melted. Avoid microwaving if possible, as it can make the sub roll chewy.

Frequently Asked Questions

Can I use rotisserie chicken instead of grilling my own?
