Start by seasoning your chicken breasts generously with salt and pepper on both sides. Heat up olive oil in a skillet over medium-high heat until it shimmers. Cook those chicken breasts for about 6-7 minutes per side until they're cooked through with a beautiful golden crust. Let them rest for a few minutes before slicing them thinly.

While the chicken is resting, slice up your avocado into thin, creamy pieces. Get your cheese slices ready, and thinly slice that red onion and tomato.

Grab your bread slices and give them some love with a nice spread of mayonnaise and Dijon mustard. This adds incredible flavor and helps create that perfect golden crust when grilling.

Time to build! On two slices of bread, layer your sliced chicken, creamy avocado, and cheese. Crown it with some red onion and tomato slices, then top with the remaining bread slices, spread-side down.

Heat up your skillet or grill pan over medium heat. Add a touch of butter or olive oil, then grill those sandwiches until they're golden brown and the cheese is perfectly melted, about 3-4 minutes each side. Give them a gentle press with your spatula to help that cheese melt evenly.
