Using a vegetable peeler, shave squash into ribbons to measure 5 cups. Discard seeds and core of squash.
Heat oil in a large nonstick skillet over medium heat. Add squash, onion, and garlic; cook 4 minutes or until onion is tender, gently stirring occasionally. Remove from heat. Add salt, red pepper, and black pepper, and toss gently to combine. Sprinkle with cheese.
I also use the peeler on the squash and add at just the last minute to pasta! End up using less of the pasta and get more veggies! This recipe here would not be bland if seasoned correctly. Squash is a veggie begging for seasoning!
We are not fans of yellow squash, but tried this recipe because of the way the squash was prepared. While the kids didn't care for the heat of the dish, my husband and I enjoyed it as well as the parm cheese on top.
