Preheat the oven to 375°F (190°C).

Cut the spaghetti squash in half horizontally. Drizzle each half with olive oil and generously season with salt and pepper.

Place the spaghetti squash halves, cut side down, on a baking pan. Roast in the preheated oven for 45 minutes to an hour, or until the squash is soft and can be easily scooped out with a fork.

While the spaghetti squash is roasting, prepare the feta and tomato mixture. In a separate baking dish, combine the crumbled feta cheese or block of feta with grape tomatoes. Drizzle with olive oil and sprinkle with salt. Roast in the oven for 30-40 minutes, or until the tomatoes are soft.

Once cooked, remove the feta and tomato mixture from the oven. Use a fork to smash the tomatoes directly in the dish. Alternatively, if you prefer a smoother sauce, transfer the mixture to a blender or food processor and blend until smooth.

When the spaghetti squash is finished roasting, carefully scoop out the strands into a large mixing bowl.

Serve and enjoy this delicious Spaghetti Squash with Feta and Tomato Sauce as a wholesome and flavorful alternative to traditional pasta.
