Toast the bread: preheat oven to 400 degrees. Slice the bread into 3/4-inch cubes. Toss bread cubes on a baking sheet with 2 teaspoons olive oil and season with salt and pepper. Place baking sheet in the oven to toast for 6-8 minutes, until golden brown.

Prep the ingredients: meanwhile, halve, pit, and thinly slice the nectarine. Halve, peel, and mince the shallot. Using a vegetable peeler, shave the zucchini into ribbons lengthwise, rotating as necessary. Toss the zucchini ribbons in a large bowl with 1 tablespoon white wine vinegar. Season with salt and pepper

Remove the bread cubes from the oven to cool. Slice the mozzarella into 1/2-inch cubes. Chop the mint leaves

Cook the chicken: heat 1 teaspoon olive oil in a large pan over medium-high heat. Season the chicken on all sides with salt and pepper. Add the chicken to the pan and cook 5-6 minutes per side, until cooked through. Set aside for 5 minutes, then dice into cubes.

Make the vinaigrette: in a small bowl, combine the shallot, remaining vinegar, and 1 1/2 tablespoons olive oil. Season with salt and pepper.

Toss the mozzarella, bread cubes, chicken, mint, arugula, nectarine, and vinaigrette into the bowl with the zucchini ribbons. Season with salt and pepper and finish with a drizzle of olive oil, if desired. Enjoy!
