Heat olive oil in a large NONSTICK pan over medium high heat until very hot. Toss chicken with 1 tablespoon pesto and add to pan along with onions, carrots and zucchini. Sauté for three minutes then add red bell pepper, orzo and garlic and cook an additional 2 minutes.
Stir in crushed tomatoes, 2 tablespoons pesto, chicken broth, chicken bouillon and seasonings. Bring to a simmer, cover and reduce heat to medium low. Simmer for 8-12 minutes, or until vegetables and orzo are tender, stirring every 5 minutes so the orzo doesn’t burn, covering pot after each stir.
Stir in Parmesan cheese. Taste and season with additional salt and pepper if desired. Garnish with fresh Parmesan and parsley (optional).
