Tools & Equipment Needed
To create a perfectly toasted, melty, deli-style sandwich, you will need:
• Skillet or grill pan
• Cutting board
• Sharp knife
• Spatula
• Tongs
• Small bowl (for assembling toppings)
• Plate for resting the cooked chicken
Optional but helpful:

• Meat thermometer (to ensure chicken is fully cooked)
Step-by-Step Instructions
Follow these detailed instructions to prepare your Chicken Avocado Melt Sandwich with perfect results:
- Season the Chicken
Sprinkle both sides of the chicken breasts with salt and pepper. This simple seasoning lets the other sandwich ingredients shine while making sure the chicken is flavorful. - Heat the Olive Oil
Add the 1 tablespoon of olive oil to a skillet and warm it over medium-high heat until shimmering. - Cook the Chicken
Add the seasoned chicken breasts to the hot skillet. Cook for 6–7 minutes per side, allowing them to become golden on the outside and fully cooked inside.
The chicken should no longer be pink and should reach a safe internal temperature. - Rest and Slice the Chicken
Remove the chicken from the heat and let it rest for a few minutes. Resting helps the juices redistribute, keeping the chicken moist when sliced. Thinly slice the chicken after resting. - Prepare the Avocado and Cheese
Slice the avocado and set out the cheese slices. Keeping everything organized makes sandwich assembly easy. - Prepare the Bread
Spread a thin layer of mayonnaise and Dijon mustard on each slice of bread. This adds flavor and prevents dryness. - Assemble the Sandwiches
On two slices of bread, layer the sliced chicken, avocado, and cheese.
Add thin slices of red onion and tomato for crispness and freshness.
Place the remaining slices of bread on top, mayo-side down. - Heat the Skillet or Grill Pan
Set it over medium heat. Add a small amount of butter or olive oil to help the bread toast evenly. - Grill the Sandwiches
Place the assembled sandwiches in the skillet. Cook for 3–4 minutes per side, or until the bread turns golden brown and the cheese is fully melted.
Press gently with a spatula to encourage even melting. - Cool and Serve
Remove from the skillet, let cool for one minute, then slice in half and serve warm.
