Slice the chicken breast into thin strips and place in a small bowl.
Toss the chicken with the dried oregano, garlic powder, cumin, sea salt, and black pepper until evenly coated.
Heat the olive oil in a non-stick skillet over medium-high heat.
Add the chicken to the skillet and cook for 5-7 minutes, stirring occasionally, until the edges are crispy and the meat is cooked through.
While the chicken cooks, dice the cucumber and halve the cherry tomatoes.
In a small ramekin, whisk together the Greek yogurt and lemon juice to create the dressing.
Place the warm cooked quinoa in the base of a bowl.
Top the quinoa with the crispy chicken, diced cucumber, and cherry tomatoes.
Drizzle the lemon-yogurt sauce over the bowl and garnish with freshly chopped parsley.
