This Chicken Walnut Pesto Sandwich is made with shredded chicken, homemade walnut basil pesto, fresh mozzarella, tomato, and arugula on toasted sourdough.
To save time, you can use leftover cooked chicken or rotisserie chicken instead of cooking the chicken breasts from scratch.
If you prefer a milder flavor, use baby spinach in place of the arugula.
For an even toastier sandwich, place the assembled sandwich in a skillet or panini press for a few minutes until the mozzarella begins to soften.
Try a different pesto sauce for a different flavor.
