Preheat oven to 400° F. and line a baking sheet with foil and spray it with cooking oil. Cut the spaghetti squash in half lengthwise and sprinkle with salt, pepper, and dried oregano. Drizzle the flesh with olive oil or spray with a little cooking oil.

Depending on the size, roast the squash on the middle rack of the oven for 35-40 minutes or until tender. Remove the squash from the oven and let it cool long enough so that you can handle it.

Using a fork, scrape the flesh out and put it in a bowl. Add olive oil, garlic powder, more dried oregano, basil, parsley, lemon zest and juice, feta and pine nuts to the squash and toss everything together. Season with more salt and pepper if needed and serve.
