Marinate the chicken with olive oil, garlic powder, onion powder, oregano, basil, red pepper flakes (optional), salt, and pepper for at least 30 minutes.
Make the balsamic glaze by simmering balsamic vinegar, honey (or maple syrup), mustard, and minced garlic until thickened.
Cook marinated chicken in a skillet until golden brown and cooked through; then coat with the balsamic glaze.
In another skillet, toast orzo in olive oil before adding chicken broth; simmer until tender.
Stir in sun-dried tomatoes, Kalamata olives, fresh basil, and Parmesan cheese into the orzo.
Combine glazed chicken with the orzo mixture; serve immediately.
