Grilled chicken, pesto mayo, melted cheese, roasted peppers, and fresh basil are layered on toasted bread for a flavorful sandwich perfect for lunch or dinner.
In a large bowl, combine olive oil, lemon juice, garlic powder, Italian seasoning, salt, and pepper. Add the chicken and marinate for at least 30 minutes.
COOK THE CHICKEN
Preheat a grill or grill pan over medium-high heat.
Grill the chicken for 4–5 minutes per side, or until the internal temperature reaches 165°F.
During the last minute of cooking, place a slice of cheese on each chicken breast and allow it to melt.
COOK THE ONIONS
While the chicken cooks, sauté the onion slices until softened and lightly caramelized.
MAKE THE PESTO MAYO
In a small bowl, stir together the pesto and mayonnaise until smooth.
TOAST THE BREAD
Lightly toast the ciabatta rolls or brioche buns until golden.
ASSEMBLE THE SANDWICHES
Spread the pesto mayo on both sides of each roll.
Layer with grilled chicken, melted cheese, sautéed onions, tomato slices, roasted red peppers, and fresh basil leaves.
Top with the remaining half of the roll.
SERVE
Serve warm with fries, roasted potatoes, a simple salad, or grilled vegetables. Bon appétit.
