Chop all the vegetables into bite size pieces. Chop the onion and garlic, mix everything together and toss with about 1/4 cup of olive oil, the Italian seasoning, salt and pepper (to taste). Preheat oven to 450 degrees. Line a large baking sheet with heavy duty foil and spread the vegis on the sheet. Roast in oven for 10 minutes, stir and roast another 10 minutes. Remove from oven and set aside. Boil pot of water and cook pasta of choice as directed. When it comes time to drain, reserve about 2 cups of pasta water, set aside. Add the vegis to the pasta, add the juice of lemon, lemon zest and balsamic vinegar. Toss all to coat. Add the pasta water, a little at a time to maintain the moisture you like. Add the parsley, toss again. Top with fresh grated parmesan cheese.
