Introduction

The Chicken Avocado Melt Sandwich is a delicious and satisfying meal that combines tender chicken, creamy avocado, and melted cheese, all nestled between toasted bread. Perfect for a quick lunch or a cozy dinner, this sandwich offers a wonderful mix of flavors and textures that everyone will enjoy.

A double-layered sandwich is sliced in half and stacked, revealing golden, crispy toasted bread on top and bottom with a slight buttery sheen. The middle layers are visually distinct: the lowest layer features thick slices of juicy grilled chicken breast, covered in gooey, melted cheddar cheese that oozes out, and a layer of fresh, diced tomatoes and red onion. Above that, a thick spread of chunky, bright green guacamole mixed with herbs covers the vegetables, contrasting with the yellow cheese and white chicken. The sandwich halves are garnished with finely chopped green herbs and rest on parchment paper atop a wooden surface. Photo taken with an iphone --v 7.0

Ingredients

2 boneless skinless chicken breasts
Salt and pepper to taste
1 tablespoon olive oil
1 avocado, sliced
4 slices of your favorite cheese (Swiss, cheddar, or provolone)
4 slices of bread (sourdough, ciabatta, or your choice)
2 tablespoons mayonnaise
1 tablespoon Dijon mustard
1 small red onion, thinly sliced
1 tomato, sliced
Butter or olive oil for grilling the sandwiches

Instructions

Step 1: Season the chicken breasts with salt and pepper on both sides.
Step 2: Heat the olive oil in a skillet over medium-high heat.
Step 3: Cook the chicken breasts for about 6-7 minutes on each side, or until fully cooked and no longer pink in the center. Remove from the skillet and let rest for a few minutes before slicing thinly.
Step 4: Slice the avocado and prepare the cheese slices. Set aside.
Step 5: Spread a thin layer of mayonnaise and Dijon mustard on each slice of bread.
Step 6: On two slices of bread, layer the sliced chicken, avocado, and cheese. Add a few slices of red onion and tomato on top.
Step 7: Top each sandwich with the remaining slices of bread, mayo side down.
Step 8: Heat a skillet or grill pan over medium heat. Add a bit of butter or olive oil to the pan.
Step 9: Place the sandwiches in the skillet and cook until the bread is golden brown and the cheese is melted, about 3-4 minutes per side. Press down gently with a spatula to help the cheese melt evenly.
Step 10: Remove the sandwiches from the skillet and let them cool for a minute before slicing in half. Serve warm.

Tips & Variations

Use ripe but firm avocados to prevent the sandwich from becoming too mushy.
Swap Dijon mustard for spicy brown mustard for a bit more kick.
Add crispy bacon or fresh spinach for extra flavor and texture.
Use a panini press for even grilling and perfect grill marks.

Storage

Store any leftover sandwiches wrapped tightly in the refrigerator for up to 2 days. To reheat, warm in a skillet over low heat or use a toaster oven until heated through and the cheese melts again. Avoid microwaving to keep the bread from becoming soggy.
