Spaghetti Squash Parmesan
This week Sunday Supper is going meatless! We’re serving up our favorites old and new, casserole style.

I’m into winter squash. I could eat it any time. Spaghetti squash is one of my go to choices. I love the texture too. I think it cooks up just ad fast as pasta. You also can prepare it so many ways. Bake it. Boil it. It doesn’t matter. It will taste the same.

For this recipe I baked the spaghetti squash cut side down in the oven with a cup of water at 350 for about 20 minutes. Let it cool just long enough to hold to shred. I just use a regular dinner fork.

While the squash bakes, you can saute your veggies. Then just mix it with the shredded squash. Top with Parmesan and mozzarella and bake. Easy right?
