Cut the chicken breast into bite-sized cubes and season evenly with sea salt, black pepper, dried oregano, and dried thyme.
Heat the extra virgin olive oil in a large skillet over medium-high heat until shimmering.
Add the chicken cubes to the skillet in a single layer and sear until golden brown and cooked through, approximately 5 to 7 minutes.
Remove the cooked chicken from the skillet and set aside on a plate.
In the same skillet, add the broccoli florets, sliced zucchini, and chopped red bell pepper, adding a splash of water if needed to help steam the broccoli.
Sauté the vegetables for 4 to 5 minutes until they are vibrant and tender-crisp.
Add the minced garlic to the skillet and cook for 1 minute until highly fragrant, being careful not to burn it.
Return the chicken to the skillet, drizzle with fresh lemon juice, and toss everything together for 1 minute to combine flavors before serving.
