Prepare the Chicken:
1. Pat the chicken breast dry with paper towels. Slice it horizontally to create two thinner cutlets, or pound it to an even thickness.
2. In a small bowl, mix 1 tbsp olive oil, 1/2 tsp dried oregano, 1/4 tsp garlic powder, salt, and pepper. Rub this mixture all over the chicken breast.
3. Heat a grill pan or skillet over medium-high heat. Cook the chicken for 4-6 minutes per side, or until cooked through and no longer pink in the center. Let it rest for a few minutes, then slice into strips or dice.
Prepare the Quinoa:
1. Cook quinoa according to package directions. Typically, combine 1/4 cup dry quinoa with 1/2 cup water or broth in a small saucepan. Bring to a boil, then reduce heat to low, cover, and simmer for 15 minutes, or until all liquid is absorbed. Fluff with a fork.
Prepare the Dressing:
1. In a small bowl, whisk together 2 tbsp olive oil, 1 tbsp fresh lemon juice, 1/2 tsp dried oregano, 1/4 tsp garlic powder, salt, and pepper until well combined.
Assemble the Bowl:
1. In a large bowl, combine the cooked quinoa, cherry tomatoes, cucumber, Kalamata olives, and mixed greens.
2. Top with the sliced grilled chicken.
3. Drizzle the lemon-herb dressing over the entire bowl.
4. Serve immediately and enjoy!
