Preheat your oven to 425°F. Toss the mixed vegetables (bell peppers, zucchini, and tomatoes) with a teaspoon of olive oil, salt, and pepper. Spread them evenly on a baking sheet.
Roast the vegetables in the oven for about 20-25 minutes, stirring halfway through to ensure even cooking.
Season the chicken breast with salt, pepper, half of the fresh herbs, and a drizzle of lemon juice.
Grill the seasoned chicken breast on a preheated grill pan or outdoor grill over medium heat for approximately 6-7 minutes per side, or until fully cooked.
While the chicken is grilling, cook the whole wheat pasta according to package instructions until al dente, then drain.
Slice the grilled chicken into strips. In a large bowl, combine the cooked pasta, roasted vegetables, and chicken slices.
Drizzle the remaining lemon juice over the salad, sprinkle with the remaining fresh herbs, and toss gently to combine.
Serve warm, and enjoy your flavorful Lemon-Herb Chicken and Roasted Vegetable Pasta.
