Preheat oven to 425°F. Toss zucchini, red bell pepper, and cherry tomatoes with olive oil, salt, and pepper, then spread on a baking sheet.
Roast the vegetables in the oven for about 20 minutes until tender and slightly charred.
Season the chicken breast with salt and pepper. In a non-stick pan, sear the chicken over medium-high heat until golden on both sides, about 4 minutes per side or until cooked through. For extra crispiness, you can coat lightly in a dusting of flour before cooking.
Meanwhile, cook the gnocchi according to package instructions until they float to the top, usually 2-3 minutes, then drain.
In a small food processor or blender, combine fresh basil leaves, garlic, pine nuts, Parmesan cheese, and a drizzle of olive oil to form the pesto. Adjust seasonings to taste.
Slice the crispy chicken and mix with the roasted vegetables and gnocchi. Drizzle the basil pesto over the top and gently toss to coat evenly.
Serve immediately and enjoy a harmonious mix of crispy chicken, hearty gnocchi, and vibrant roasted vegetables accented by fresh basil pesto.
