This Cheesy Chicken Avocado Melt Sandwich combines tender grilled chicken, creamy avocado, gooey melted cheese, and fresh greens, all toasted to perfection between crispy slices of bread. It’s the ultimate comfort food with a healthy twist!
In a small bowl, whisk together mayonnaise, lime juice, garlic powder, and a pinch of salt and pepper.
Spread the mayo mixture on one side of each slice of bread.
Layer on one slice: cheddar cheese, sliced chicken, avocado, then remaining cheese. Top with the second slice of bread, mayo-side down.
Heat butter or olive oil in a skillet over medium heat. Place the sandwich in the skillet and cook until golden brown and cheese starts to melt, about 3–4 minutes per side, pressing gently with a spatula.
Remove the sandwich from the skillet, let it rest for a minute, then slice in half and serve warm.
