I made this one day because I had these ingredients on hand. My husband too the left overs to work the next day and heated it up in the microwave. Everyone in the office called and asked me for the recipe. Since I didn't have one, I had to write it down for them. Enjoy!
Put small amount of olive oil in a large frying pan. Heat pan to medium-high and add chicken. Saute until almost done, 5 to 10 minutes. Add onion and zucchini and cook for 3 to 5 minutes. Add garlic and cook for 1 more minute. Add tomatoes with liquid and Italian seasoning and cook for about 5 minutes. Taste and add Italian seasoning, salt and pepper to taste.
While chicken mixture is cooking, bring 8 cups of salted water to a boil. Add pasta and cook according to package directions (usually 7 to 9 minutes). When done, drain and put in a large bowl. Add pesto and toss.
To serve, put pasta on plates and spoon chicken mixture over top. Grate fresh parmesan cheese over top. Serve immediately.
