Ingredients
- 2 boneless, skinless chicken breasts
- 4 slices thick sourdough bread
- 4 slices bacon
- 1 avocado, sliced
- 1 large tomato, sliced
- 1/2 red onion, thinly sliced
- 2 slices cheese (Swiss, provolone, or cheddar)
- 4 leaves crisp lettuce
- 2 tbsp mayonnaise or preferred sandwich sauce
- 1 tbsp olive oil
- to taste salt and black pepper
Instructions
- 1Season the chicken breasts

Place the raw chicken breasts on a clean wooden cutting board. Season them generously with salt, freshly ground black pepper, and a drizzle of olive oil, rubbing the seasonings evenly into all sides to enhance flavor and ensure proper searing.
Tip: Rub the oil and seasonings into the meat thoroughly before cooking to create an even crust. - 2Grill the seasoned chicken

Place the seasoned chicken breasts into a preheated black grill pan over medium-high heat. Allow them to sear undisturbed for several minutes to develop distinct grill marks on the surface before flipping.
Tip: Do not move the chicken too early, or it will stick to the pan and fail to develop a proper sear. - 3Slice the red onions

Place a peeled red onion on the wooden cutting board and use a sharp knife to cut it into thin, uniform slices. Thinly slicing the onion ensures a crisp texture and manageable bite for the sandwich.
Tip: Use a sharp chefs knife to make clean cuts and prevent crushing the onion layers. - 4Prepare the bacon strips

Lay the raw bacon strips out flat and straight on a green preparation tray, checking them for quality before cooking. Keeping them flat prevents overlapping and ensures they cook evenly when transferred to the heat.
Tip: Arrange bacon in a single layer to avoid sticking and uneven rendering of fat. - 5Spread sauce on sourdough bread

Take thick slices of sourdough bread and use a spoon or spatula to spread an even layer of flavorful sauce across the surface. Ensure the sauce covers the bread evenly to bind the sandwich ingredients together.
Tip: Spread the sauce right to the edges so every bite has full flavor. - 6Toast the bread in a pan

Place the prepared slices of bread into a hot pan, pressing them down gently with a press or spatula. Toast until the bottom turns golden brown and crispy, developing a crunchy texture.
Tip: Monitor the heat closely to prevent burning while achieving an even golden crust. - 7Assemble the sandwich

Spread condiments onto the toasted bread, then layer with crisp lettuce, cooked bacon, sliced tomatoes, grilled chicken, cheese, red onion, and avocado to complete the sandwich.
Tip: Layer heavier items like chicken and cheese closer to the bread to keep the sandwich stable when slicing.
