My counter was covered with some tomatoes and squash that I needed to do something with and this is what I came up with. You can substitute with zucchini if you like. It is also good poured into a baking dish and topped with mozzarella cheese and baked for 15-20 minutes!
Heat large skillet till hot. Add olive oil then diced onions, peppers. Sautee 2-3 minutes then add garlic and diced squash, Italian seasonings, oregano, bay leaf, celery seed, crushed red pepper, salt & pepper. Sautee 5-7 minutes till squash is tender.
Add mushrooms stir for a minute then add in tomatoes and juice. Bring to a boil, taste to see if you need more salt or pepper, then cover and reduce heat.
Simmer 20 minutes. Add in a little of the pasta water and parsley. Bring to boil, stirring uncovered for 2-3 minutes. Toss with a hearty pasta like shells, penne or ziti. Top with fresh grated parmesan if desired.
