Season the cubed chicken breast with paprika, garlic powder, oregano, salt, and pepper.
Heat two tablespoons of olive oil in a large skillet over medium heat and cook the chicken until golden and cooked through, about six to eight minutes.
Chop cucumbers, cherry tomatoes, red bell pepper, and red onion while the chicken cooks.
Cook quinoa or brown rice as the base for the bowl according to package instructions.
Assemble the bowl by placing a scoop of quinoa or rice at the bottom. Layer with cooked chicken, chopped vegetables, Kalamata olives, and crumbled feta.
Drizzle with olive oil and lemon juice. Sprinkle fresh parsley on top.
Serve immediately, or store components separately in the fridge for meal prep.
