This chicken pesto sandwich is a simple but filling recipe that makes for the perfect lunch! A toasted ciabatta loaf loaded with mayonnaise, pesto, melty provolone, juicy chicken, and shredded lettuce, this cafe-style ciabatta sandwich is also perfect for making ahead of time for an easy grab-and-go meal.
In a bowl, add the chicken thighs, 1 tablespoon of olive oil, salt, pepper, garlic powder, and paprika. Mix until the chicken thighs are well coated.
In a grill pan (or grill or regular sheet), heat up 1 tablespoon of olive oil over medium heat. Once the pan is hot, add the chicken thighs smooth-side down and cook for 5 minutes. Flip and continue to cook for 6 to 7 minutes or until cooked through. Set aside.
Slice the ciabatta in half lengthwise and then generously spread mayonnaise on the cut side. Place the ciabatta on a sheet pan and broil the bread for 5 minutes or until they are as golden and crispy as desired.
Generously spread the pesto over the layer of mayonnaise and add the four chicken thighs to the bottom half of the sliced loaf.
Layer a single layer of sliced cheese over the chicken, transfer it back to the oven, and broil for another minute or until the cheese has melted over the chicken thighs.
Add the shredded lettuce over the top of the melted cheese and then top it with the top slice of bread over the top.
Depending on your preference, press down and slice the bread into thirds or halves.
