Preheat your oven to 425°F and line a large sheet pan with parchment paper for easy cleanup and even roasting.
Cut the chicken breast into 1-inch bite-sized pieces and place them in a large mixing bowl to ensure even seasoning.
Slice the zucchini into half-moons, chop the red bell pepper into 1-inch pieces, and trim the woody ends off the asparagus before cutting them into 2-inch lengths.
Add the vegetables to the bowl with the chicken, then drizzle with the extra virgin olive oil.
Sprinkle the minced garlic, dried oregano, dried thyme, sea salt, and black pepper over the mixture and toss thoroughly to coat every piece.
Spread the chicken and vegetables in a single layer on the prepared sheet pan, making sure not to overcrowd the pan so the vegetables can caramelize rather than steam.
Roast for 15 to 18 minutes, or until the chicken is golden and reaches an internal temperature of 165°F.
Remove from the oven and immediately finish the dish by drizzling with fresh lemon juice and a sprinkle of lemon zest for a bright, aromatic finish.
