In large skillet, over medium-high heat, heat olive oil and saute garlic for 2 minutes. Add chicken, pepper and Italian seasoning, and cook, stirring occasionally, until chicken is no longer pink.
In medium bowl, stir together onion soup mix, cream of mushroom soup, milk and water. Add to chicken mixture. Add peas and Parmesan to chicken, bring to a boil, then reduce heat and simmer 15 minutes, stirring occasionally.
While sauce is simmering, bring a large pot of lightly salted water to a boil. Add pasta and cook for 8 to 10 minutes or until al dente; drain.
