Introduction

The Chicken Avocado Melt Sandwich is a delightful combination of juicy, seasoned chicken, creamy avocado, and melted cheese, all nestled between crispy toasted bread. It’s a perfect meal for lunch or a casual dinner, offering fresh flavors and satisfying textures in every bite.

The sandwich has three layers of toasted golden-brown bread with a crispy texture and sprinkled green herbs on the top slice. Between the bread layers are thick, juicy slices of grilled chicken breast, melted orange cheddar cheese oozing out, fresh green guacamole with chunks of avocado, diced red onions, and red tomato slices. Small bits of chopped herbs are scattered around the sandwich. In the background, blurred, there is half an avocado and a white bowl with a purple dip. Photo taken with an iphone --ar 4:5 --v 7

Ingredients

2 boneless skinless chicken breasts
Salt and pepper, to taste
2 tablespoons olive oil (for cooking chicken)
1 ripe avocado, sliced
4 slices cheese (Swiss, cheddar, or provolone)
4 slices of bread (sourdough or ciabatta recommended)
2 tablespoons mayonnaise
1 teaspoon Dijon mustard
¼ cup red onion, thinly sliced
1 medium tomato, sliced
Butter or olive oil, for grilling

Instructions

Step 1: Season the chicken breasts generously with salt and pepper on both sides to enhance the flavor.
Step 2: Heat olive oil in a skillet over medium-high heat. When shimmering, add the chicken and cook for 6-7 minutes per side, until fully cooked and no longer pink inside. Let the chicken rest for a few minutes before slicing.
Step 3: While the chicken rests, slice the avocado, cheese, red onion, and tomato. Prepare all ingredients for quick assembly.
Step 4: Spread mayonnaise and Dijon mustard evenly on each slice of bread. On two slices, layer sliced chicken, avocado, cheese, red onion, and tomato. Top with the remaining bread slices, mayo side down.
Step 5: Heat a clean skillet or grill pan over medium heat. Add butter or olive oil, then place the sandwiches in the pan. Grill for 3-4 minutes per side, pressing gently with a spatula to melt the cheese and create a golden crust.
Step 6: Remove the sandwiches from the pan once golden and cheese is melted. Let them cool for a minute, then slice in half and serve warm.

Tips & Variations

Don’t rush cooking the chicken; ensure it’s fully cooked but still juicy.
Use room-temperature mayonnaise and mustard for smoother spreading.
Try different cheeses or mix two for unique flavors.
Add fresh spinach or arugula for extra crunch and nutrition.
Watch the grill closely to avoid burning the sandwich.

Storage

Store leftover sandwiches wrapped tightly in the refrigerator for up to 2 days. To reheat, warm in a skillet over low heat to preserve crispiness and remelt the cheese, or use a toaster oven. Avoid microwaving if possible, as it may make the bread soggy.
