Ingredients
Method
1. Cook the Chicken
Start by seasoning both sides of the chicken breasts with salt and pepper. Heat olive oil in a skillet over medium-high heat. Place the chicken in the pan and cook for about 6–7 minutes per side, until the meat is fully cooked and no longer pink in the center.Transfer the chicken to a cutting board and let it rest for a few minutes. This helps keep the chicken juicy. Once rested, slice it thinly.2. Prep the Fillings
Slice the avocado and prepare the cheese slices so everything is ready for assembling. Having ingredients prepped ahead makes the sandwich-building process quick and smooth.3. Prepare the Bread
Spread mayonnaise and Dijon mustard evenly on one side of each slice of bread. This adds flavor and helps create that rich, creamy layer inside the sandwich.4. Build the Sandwich
Lay two slices of bread on your work surface, sauce side up. Layer on the sliced chicken, followed by avocado and cheese. Add a few slices of red onion and tomato for extra flavor and freshness.Place the remaining slices of bread on top with the spread facing down.5. Grill the Sandwiches
Heat a skillet or grill pan over medium heat and add a small amount of butter or olive oil. Place the sandwiches in the pan and cook for about 3–4 minutes per side, until the bread turns golden and crisp and the cheese melts.Press gently with a spatula while cooking to help everything heat evenly.6. Serve
Remove the sandwiches from the pan and allow them to cool briefly. Slice them in half and serve warm while the cheese is still deliciously melty.Notes
