GF used one of them veggie peelers that does the julienne strips, and she strips a zucchini and a yellow squash in long shreds that resemble cooked pasta noodles. She seasons them in a little evoo, salt & pepper, chopped garlic, thinly slice and chop half a red onion, add some sliced red or yellow bell pepper, stir, cover and saute over medium heat stirring as necessary until veggies are fork tender.
You can serve this as is, it's delicious and VERY healthy, you can put marinara or meat sauce on it to make it like spaghetti, you could use it anywhere that pasta noodles are used, you can add it to cooked pasta noodles, top with grated parmesan/romano cheese, you could make a scampi with it as well, quite versatile in what you can do with it.
