Slice the chicken breast into thin, bite-sized strips and place them in a small mixing bowl.
Toss the chicken with the olive oil, dried oregano, garlic powder, cumin, sea salt, and black pepper until evenly coated.
Heat a large non-stick skillet over medium-high heat and add the seasoned chicken in a single layer.
Sear the chicken for 3-4 minutes per side until the edges are golden-brown and crispy and the meat is cooked through.
While the chicken cooks, prepare the salad by combining the diced cucumber, halved cherry tomatoes, minced red onion, and chopped parsley in a bowl.
In a separate small ramekin, whisk together the Greek yogurt, lemon juice, and dried dill to create a creamy dressing.
Assemble the bowl by placing the warm cooked quinoa at the base.
Top the quinoa with the crispy chicken strips and the fresh vegetable salad.
Drizzle the lemon-dill yogurt sauce over the entire bowl and serve immediately.
