and sprinkle on salt and pepper, then toss everything so the pieces get evenly coated. Cook for about 5 minutes, stirring occasionally, until the bread turns golden and crisp on the edges.
Slice your chicken breast horizontally into thin cutlets, then season both sides with Italian seasoning and salt. In the same skillet you used for the croutons, heat a tablespoon of olive oil until it shimmers. Add the cutlets and cook about 4 minutes per side, until golden and cooked through, then set them aside to rest.
While the chicken rests, divide the spinach, torn basil, halved tomatoes, and mozzarella pearls among your serving bowls. Give everything a light sprinkle of salt and pepper so the vegetables and cheese pick up seasoning before the toppings go on.
Scatter the warm croutons over each bowl of greens, then slice the rested chicken and layer it on top. Finish with a generous drizzle of good olive oil and balsamic glaze. Serve it right away while the chicken is still warm and the croutons are crunchy.
