Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Dice the zucchini and red bell pepper into bite-sized pieces and spread them evenly across the prepared baking sheet.
Drizzle half of the olive oil over the vegetables, season with a pinch of salt and pepper, and roast for 20 minutes until tender and slightly caramelized.
While the vegetables roast, cook the whole wheat penne in a pot of boiling salted water until al dente, then drain and set aside.
Slice the chicken breast into thin strips and season them with the dried oregano and the remaining sea salt and black pepper.
Heat the remaining olive oil in a large skillet over medium-high heat and sauté the chicken until golden brown and cooked through.
Add the minced garlic to the skillet with the chicken and cook for about 1 minute until fragrant, being careful not to burn it.
Zest and juice the lemon directly into the skillet, stirring to deglaze the pan and coat the chicken.
Add the cooked pasta and roasted vegetables to the skillet, tossing everything together over low heat to combine the flavors.
Garnish the dish with fresh chopped parsley and grated parmesan cheese before portioning into containers for a perfect meal-prep lunch.
