Slice the chicken breast into bite-sized pieces and season evenly with sea salt, black pepper, and dried oregano.
Quarter the baby potatoes, slice the zucchini into half-moons, and trim the woody ends off the asparagus spears.
Heat the extra virgin olive oil in a large skillet over medium-high heat until shimmering.
Add the baby potatoes to the skillet and cook for 5 minutes, stirring occasionally, until they begin to brown and soften.
Move the potatoes to one side of the pan, add the chicken pieces, and sear for 4 minutes until golden on all sides.
Toss in the zucchini, asparagus, and minced garlic, then sauté everything together for 3 more minutes until the vegetables are tender-crisp.
Remove the skillet from heat, drizzle with fresh lemon juice, and garnish with chopped parsley before serving hot.
