Grill the Chicken: Season the chicken breast with salt and pepper. Heat olive oil in a skillet over medium-high heat. Grill for 5–6 minutes per side until fully cooked.
Glaze: Once cooked, remove the chicken from the heat. Brush 1 tablespoon of pesto over the warm chicken and let it rest for 5 minutes before slicing into strips.
Prepare the Zoodles: In the same pan, add the zucchini noodles and sauté for just 2 minutes—they should be tender yet crisp (al dente). Do not overcook.
Toss: Remove the zoodles from the pan and toss them with the remaining 1 tablespoon of pesto and cherry tomatoes.
Assemble: Place the pesto-coated zoodles in the main compartment of your bento box. Top with the sliced grilled chicken.
Garnish: Sprinkle with toasted pine nuts and shaved parmesan cheese for a gourmet finish.
Storage: Refrigerate until ready to serve.
