1. Season the Chicken: Start by seasoning the cubed chicken with a sprinkle of salt, pepper, oregano, and basil.

2. Sauté the Chicken: Heat the olive oil in a large skillet or pot over medium-high heat. Add the seasoned chicken and cook until lightly golden and cooked through, about 5-6 minutes. Remove the chicken from the skillet and set it aside.

3. Cook the Aromatics: In the same skillet, add the diced onion and minced garlic. Sauté these fragrant ingredients until they become soft and fragrant.

4. Add the Orzo and Broth: Pour in the chicken broth and add the orzo pasta. Bring the mixture to a gentle boil, then reduce the heat and let it simmer for 8-10 minutes, stirring occasionally, until the orzo absorbs most of the broth.

5. Stir in the Veggies: Add the chopped spinach and halved cherry tomatoes to the skillet. Return the cooked chicken to the mix and cook for an additional 2-3 minutes, just until the spinach wilts and the chicken is warmed through.

6. Serve and Enjoy: Give the High Protein Chicken Orzo a final taste and adjust the seasoning with salt and pepper as needed. Serve hot, garnished with a sprinkle of grated Parmesan cheese if desired.
