Slice the chicken breast into bite-sized pieces and season evenly with the sea salt, black pepper, and dried oregano.
Bring a small pot of water to a boil and cook the potato gnocchi until they float to the surface, then drain and set aside.
Trim the woody ends off the asparagus and cut the spears into 1-inch pieces.
Heat the olive oil in a large skillet over medium-high heat and add the chicken pieces.
Sear the chicken for 5-6 minutes, turning occasionally, until golden brown and cooked through.
Add the minced garlic, asparagus, and green peas to the skillet, sautéing for 3-4 minutes until the vegetables are tender-crisp.
Stir in the cooked gnocchi and fresh lemon juice, tossing everything together for 1 minute to allow the flavors to meld.
Garnish with freshly chopped parsley and serve immediately.
