1 medium onion, diced
1/3 cup olive oil
1 minced garlic clove
2 cups yellow squash, diced
2 cups zucchini, diced
10 medium leaves fresh basil, chopped
Black pepper and salt to taste
1 cup fresh Parmesan cheese (at least)
cook pasta according to package directions. Meanwhile, saute onion in olive oil in a skillet over medium heat for 6 minutes, Add garlic and saute for 2 minutes. Add yellow squash and zucchini and cook for an additional 6 minutes. Stir in basil and pepper and salt. Toss sauce over pasta and sprinkle with Parmesan cheese.
I really, really liked this dish. I did need to add quite a bit of pepper and salt for more flavor and lots of Parmesan cheese.
