Pat the chicken breast dry and season both sides evenly with sea salt, black pepper, garlic powder, and dried oregano.
Heat the extra virgin olive oil in a non-stick skillet over medium-high heat.
Place the chicken in the skillet and sear for 5-6 minutes per side, or until golden brown and the internal temperature reaches 165°F.
While the chicken cooks, dice the cucumber and halve the cherry tomatoes.
In a large serving bowl, combine the cooked quinoa, chickpeas, diced cucumber, and cherry tomatoes.
Remove the chicken from the pan, let it rest for 3 minutes, then slice into thin strips.
Add the sliced chicken to the bowl and drizzle with fresh lemon juice.
Garnish with chopped fresh parsley and toss everything together to combine before serving.
